The ship may have sailed on implementing substantial changes without making people unhappy, but if I could magically make everyone forget what they had, this is what I would suggest:
Alpha: Make the level shift incarnate only. It made normal content too easy. Fine otherwise.
Destiny: Tone down the numbers on Barrier. Fine otherwise.
Lore: Some outliers need to be way toned down, like BP and Longbow. Currently Lore out damage most players, which shouldn’t be the case.
Hybrid: remove the active component but leave the passive (maybe small buff to the passive)
Interface: perfect as is
Judgement: perfect as is. Maybe make some of the less popular ones a little more attractive
