Make Maim (I forgot the 2nd part of single target rotation weaponskill name) apply DOT.

Or make Upheaval apply DOT, something like 250 potency with 40 potency for 15s.

WAR lack DOT to make enemies bleed, even though technically axe is still a blade weapon.

Onslaught-wise, retain the gauge cost but give a conal aoe effect of 20 potency to every other target other than the first (maintain 100 potency).

Some greedy thing about future 6.0 will be giving a trait to lv90 that change FC to IC and the AoE skill to Chaotic Cyclone during IR. And based on other class lv90 performance, add nascent glint effect to IR to all other party members (broken it is, so only when all other lv90 are equally broken).

Roleplay wise, make Inner Chaos proc a tumbling effect against normal mobs. (As in, Dohn Mheg First Boss Water Jet attack that flings you to the sky) Because it is funny and Inner Chaos looks like a crazied golf club swing.
