That shouldn't be an arguing point here. I understand all of this is based on something, and you stand by your decisions. But when you look at the data, how many people enjoy "playstyle as tool weaponmaster" and all of them agree that its a dead end mastery cause of "ryo burden" something is badly designed there. It shouldn't be so detrimental.
If I threw a Kunai at something, can I not pick that up? Did it vaporize? I can see that maybe it was damaged, maybe beyond repair. But I would still throw a broken Kunai over none. What anime related character is carrying 200 of each tool in their satchel? None. It's not realistic, and it can be changed. Just make thrown weapons permanent, 10 cast per 180 sec, and cost 100 times more or something.
None of your monsters generate a way to "accrue" finances past the burden of tool ninjas. Unless I get and sell blank scrolls to other players at the rate of 1/150 or so (napkin math) I wont afford my tools. And I won't have any jutsus either cause I sold all my scrolls. And I would be taking every bit of loot from my party.
Crafting was thrown in as an option, as it would breathe new life into the game if we had something to gather material wise. New areas to fight for control. So much potential.
I enjoy lots of things in your game, mostly the playerbase. I offer opinions, and feedback, as a player perspective, and to tell me to do something else, is kind of insulting on a small level. You should open yourself up to debate and criticism more often, I think it would benefit not only the community as a whole, but yourself as a developer. Most dev's these days do polls on the community to make changes, what to focus their resources on, to bring the community in. If you polled about weaponmaster, you would hear a lot of "rework needed".
I hold nothing against you for your decisions, but I will speak my mind about things I don't like. And yes, most likely, I will stop playing this unrewarding mastery until it is changed, like everyone eventually does.
