Great feedback, thanks everyone. Damage-wise I think I'm usually pretty okay, it's just I'm sometimes too late with my Inner Beast for tank busters. Fights that "worry" me in particular would probably be stuff like Mog EX (lots of tankswaps) and Ramuh EX (lots of tank swaps and stacks management) and, more recently, Nidhogg EX (but here I just get demolished by adds despite popping CDs and eventually Holmganging, so I'm going to assume DPS was too low).

I should probably just re-watch guides for these fights, queue up, and try my best.
