I want to talk about Body Flicker Pads, that allow players to get teleported to a set destination and the fact that in order to use them, you are absolutely forced to give up one of the few very precious jutsu slots. But also, how the game forces this decision on you and only gives the illusion of a choice.
Flicker Pad functionality
Before I come to my suggestions, here is what I am talking about:
On the screen there are 2 Body Flicker Pads that teleport you onto the hill or down from the hill when you touch them. But this will only happen, if you did learn ,,Body Flicker Technique". The level of this technique does not matter for the Body Flicker Pads to work, as long as you did learn it at all.
There are a number of jutsus that let you teleport or that also have ,,flicker" in the name like Lightning Cutter Technique or Flash Flicker, but Flicker Pads only do something if you have Body Flicker learned. Otherwise you will just walk over them and nothing happens at all.
Body Flicker in itself is a jutsu that also can be actively used in order to instantly teleport to a nearby target at the cost of a few chakra points. This said, using a Flicker Pad will not consume any chakra nor will it set the Body Flicker Technique on cool down.
Now, on its own, having a requirement in order to advance somewhere is a nice concept. This might be quest lines that opens up a path to a new boss or a hidden secret that unlocks a certain passage. In the past, the number of jutsus that a player could learn were not limited and thus it was a nice idea to have players put efford into aquiring just another jutsu into their collection in order to use those previously inaccessible teleportation devices. Furthermore, those Pads used to be just shortcuts for areas that were otherwise still accessible by making a detour.
However, there are 2 changes or additions that create a really nasty mandetority. Each alone is nothing serious, but it is the combination of those two that creates an issue:
1. There had been places added that are by no other means accessible aside from using a Flicker Pad or by using unintended behavior like duelling someone with substituation jutsu active and stepping onto an explosive tile to teleport to him (Which works in the Lv 30 Arc at the Raccoon Hill). But even by doing those unintended workarounds, there are still some truly unreachable places like the Cursed Host filled chasm, the Abanddoned (Snake) Lair's deeper floors or Leaf Village's Sewer house; just naming 3 that instantly come to my mind. But even if you can cheese the Raccoon Hill in Arc 30 with another player, if you are playing without another player or Lightning as your mastery, then you are effectifly stuck and unable to ever finish arc 30, if you do not posses the Body Flicker Technique.
2. The second change is the heavy limitation of the number of jutsu slots. The incentive behind might be for balancing reasons to have players carefully choose one jutsu over another and limit their power and have them make decisions. But at the same time, it creates a mandetority to have useless skills be dropped and ignored, in order to fill those slots with better skills.
Now... each on their own, those two things are harmless: if you have limited areas that require a certain jutsu to access, it is not an issue, if you do not have to worry about carrying dead and useless jutsus, if the number of jutsus that you can posses aren't limited. And having a limited number of jutsus is not an issue in playing the game, if all places are still reachable by making detours, as long as you can reach everywhere.
But having those 2 things combined does create problems: You will never be able to finish the Snake Lair missions or enter the boss fight like this. The Cursed Host cave will be forever a dead end and the boss at the end or the whole cursed Laboratory will be off-limits for you. And an enemy player can literally go afk for hours mid fighting on the other side of the Leaf Sewer chasm without you ever being able to get to him. And as already mentioned above, you will never be able to finish Arc 30 on your own.
What previously was more of an inconvenience did now turn into a mandetory illusion of choice that appears to you with the ability to unlearn Body Flicker if you do not need or want it, but it actually forces you to have it learned at the cost of more valuable skills that you can not learn anymore because of this fact.
Now, personally I would love to see the entire Body Flicker requirement be gone for good and have those Flicker Pads just always work. This would leave Body Flicker as a jutsu that players actually can learn or not learn based on the decision if or if not they want to use the Body Flicker skill itself in combat or to jump up a ledge instead of walking around.
However, it would oppose the initial idea of having Flicker Pads be something to work for and it would reduce the already few numbers of actual things that a player can archieve and unlock in terms of locations and secrets. And it would also keep an even better sense of archievement, if a function is not available from the very beginning.
Therefore I want to bring forward a few suggestions that would ideally keep a sense of archievement, but also will actually respect the player's choice of skills without forcing a decision onto them.
Since a lot of things in this game are already limited by level, Flicker Pads could be just another thing that are affected by it.
This could be the whole Flicker Pad system unlocking upon reaching a certain level, but a certain level could also be unlocking only specific Flicker Pads, effectively making certain areas level-locked.
It makes sense that a player who is more knowledgeable learns to use more devices and functions of the world he lives in.
Having or not having Body Flicker will not have any effect on Flicker Pads anymore.
No requirement at all:
Now this is a cheap solution that would require the least amount of efford: simply have Flicker Pads always work unless it is tied to specific conditions like belonging to a certain village or quest progress.
The downside here is that the feeling of archievement is lost though.
Individual Flicker Pad unsealing:
On the other hand, it is also an idea to fully embrace the origin of having a player work for their archievement by having them unlock each Flicker Pad individually.
This could be done rather straight-forward by buying unsealing scrolls for specific Flicker Pads inside a village shop...
...but especially the more interesting Flicker Pads can be attached to some sort of challenge or quest like the Snake Lair Flicker Pad.
...And some Flicker Pad Unsealing Scrolls could even be rare drops that players can work for.
Once unlocked, those Flicker Pads will remain unlocked.
Reworked Jutsu list:
Another approach is to take care not on the archievement-part but on the consumption of very precious jutsu slots.
For instance, the Jutsu List can be separated into categories like ,,Common Jutsus", which are not bound by a mastery, ,,Mastery-Jutsus" where jutsus go that belong to one of the 8 Specializations & Masteries, and ,,Corps Jutsus" where jutsus go that require you to be part of a certain group.
So there could still be a limit of the number of jutsus for the ,,Mastery-Jutsus" group, but no limit for the ,,Common Jutsu" and the ,,Corp Jutsu" lists.
There could also be a category ,,Free Jutsus" where Common jutsus go that are deemed necessary and which will not consume a skillslot of any of the other groups. This would be an infinite sub-category of ,,Common Jutsus" and allows to still have a set limit on ,,Common Jutsus".
Activated Flicker Pads
Have Flicker Pads which are permanently activated without requirement, if the Flicker Pad's destination can not be reached by making a detour.
This will still allow Body Flicker to have its use for taking short cuts, but it will remove the necessarity of forcing a player into having Body Flicker to even progress at all.
Obviously that list of suggestions is not complete and there may be other suggestions that I did not think of. If you have another suggestion or an improvement to a suggestion of mine, feel free to share your opinion.
I am also well aware, that this very issue only becomes an issue, if a player does not absolutely necessarily want to have Body Flicker for combat anyways. But the way Body Flicker Pads are currently set up removes the choice from a player and practically declares Body Flicker Technique being mandetory while pretenting it is not. And this is a messy situation that needs rethinking.
