My expectation:
1) Wheeling Thrust and Fang and Claw replace True Thrust and are no longer placed on hot bars. Combo becomes:
True Thrust -> Disembowel -> Chaotic Spring -> [Wheeling Thrust/Fang and Claw/Raiden Thrust] (same button) -> Vorpal Thrust -> Heavens' Thrust -> [Fang and Claw/Wheeling Thrust/Raiden Thrust] (same button) -> Disembowel (Repeat)
2) AoEs become CIRCLES!!!!!!!!!!
I honestly, can't think of anything else that they would do. Which is really scary tbh.
