Thus far the highest legit exp numbers are from 2 dps + 4 support + outside healing, how you're going to imply that 3 dps + 3 support would somehow be better, I'm really not sure. At this point 2 ah sams can be sufficient dps for 25k/hr, merit situations where the blu would need to be all out pure dps are not top quality groups.
I mean... honestly you could grab 2 melee capable of a top notch level kill speed, bring brd brd rdm,
sub sch and fill the WHM role more efficiently than a whm can do it...
