I have tested the rev every BWE and did find mallyx very unique and fun, if a bit awkward at times. I have read many suggestions and much complaining on the forums about the most recent changes most of it I disagree with; but the last suggestion you make about sacrificing your own boons to put out an equal amount of corruptions sounds like it would be both fun and balanced, and have great synergy with glints auras. I would love to play that style in pvp and pve. It would also have that big wow moment the devs and players like to see happen in combat. It captures the feeling of the original play style (evil demon manipulating corruptions) with out having a strange counter synergy in group play.
