I never said you need 4 maras. I just argued that is gives an unfair dps advantage with no downside in current content.
Ps. It would be more efficient to stagger the BT's. ~1/min.
Re: the entire Marauder/sentinel debauchery in this thread..
as long as you dont NEED 4 maras to down end-game content, i think its fine. With that aside i think the devs should focus more on making the NiM version live up to Heroic raids in WoW. Nim operations are targetted towards the raider raiders right? NiM ops definitely do not have to be clearable in 2 days upon release.
