@Rory Would you want assistance designing missions? I could get behind that! If that was something you've considered needing help with, I wouldn't mind presenting ideas to you in a structured format such as:
Questline
Quest path
Prerequisites
Interactions
NPC Dialog and Replies
Objectives
Rewards
Dev resources needed (new NPC, new item, new vendor, etc.)
It would be neat to have quests related to certain masteries for advancements, or general RP qualites. For instance since I am water aspect, I would need to cast 100 Water Slashes while in a body of water to advance my training. (easily done and not much creative thought behind that).
Anywho, let me know and I'd start trying.
Love your game!
