I have used the assist in both EX trials as a war and pld. MT/ST for Wep EX. it doesnt use the new skills like primal rend or Confiteor combo sword . I have tried to only control the movement. the parsing is significantly lower than my manual inputs but it does the job. Ive been dungeon assist with bard and blm 81+, its alright. i think trials will be the same as well, it just wont press the new skills.
