To give you an idea, on our first kill, no i115 weapon (all 110), no potions, a couple of i120 pieces per people, almost zero total i110 crafting pieces (maybe a couple spread over the whole raid), warrior fully i90 ruby melded pieces + 30 STR and pld maintanking, healers doing zero damage, we had :

Sch and whm 0
Pld ~150
War~275
Brd~360
Smn~350
Nin~380
Mnk~390
LB~140

Total about 2045 dps. Beat the enrage by about 10 seconds.
