meh lets not start with DGs again...
3 Titan 6
4 DG after nerf
from 1 -7 is real simple... 8th is depending on how smart is your group / healers dps, can either be incredibly easy, or stuck on it for lack of awareness... 10-12 are really hard fights... trasher need tricks, like snipers, and practice... olok P2 is simple if tanks know what they doing, but it can get really messy and long fight makes it more annoying that actual trasher 2 min wipes
... styrak is, well, hard, until your group figures out whats everyone doing, once u figure out whats everyone doing and luck on who gets the first nightmare, it can be moved to the 1-7 easy fights, its just repeat the execution of "barely" hard mechanics 7 straight phases, only thing that can go wrong is if he decides to do a super saiyan Overload and tank gets knocked off from wall too far from wall, or **** like that, then he starts playing soccer with you thru the whole room /facepalm lol, and jump is almost an instant kill on a non tank.
