I'm currently on turn 5 and Levi ex. Unfortunately I have an old ps3. I can dodge everything with Twin on time, but in that fight my weaponskills (DRG) reset more often than not, and this really hurts my DPS and the group. On Levi ex, the tail and the Sahagin adds don't span on time, so I can't even target them.

That said, Titan ex is a cakewalk for me, and I personally feel fights like that are much easier with controller, especially if you're monk.
