I know everyone has their own opinion, but I'd like to hear some reasons why one is better then the other. I've seen both classes own and both fail, so if anything I'd like some valid reasons why one is better then the other... not any "qq" over a class.
My 4 man would be a combination of Sorc (Healer), Merc (healer), PT (Tanky DPS) and an Operative.
Oh, and I'm going to fill a DPS roll.
Thanks.
