I think diadem could be better if they added more widespread focus on incentive, perhaps a generous amount of poetics, eso - maybe have its own type of maps that are diadem-specific(skypirate maps) which could offer a way to either force spawn the star ranks instead of just killing tier 4's till the big labowski spawns and zerg it down, another problem when it was getting popular was getting credit for them if you had the unfortunate run with several other groups that were in it, maybe the maps could offer umbrite, and unidenified items as well as a good amount of poetics and esoterics?
