I play on the PS3 and I'm a black mage. I've gotten to the point of almost beating twintania (8% health, we died to enrage cause we were holding dps to build LB!) but honestly I could not have done it without the assistance of people calling out twisters for me on team speak.

I agree that even with the limited buttons to press quickly we can still do just fine (sometimes even better) in battle than PC players but the lack of FOCUS TARGET is the one REAL issue.
Thankfully we are finally getting that on Dec. 17th.
