Hadn't touched it beyond leveling it to 70, picked it up on a dummy yesterday with a hodgepodge of BiS, Susano book and 300-310 gear and did 4145 on a dummy. No food, pots, or party buffs, just me alone. I'd say it's pretty strong - top logs show around 1800 more than that, so I'm sure the class is definitely capable of more with things like an AST, NIN, and BRD in the group, as well as proper raid prep and better gear. It may have possibly been OVERBUFFED with 4.1, but time will see, I suppose.
