Heh. I'm just gonna go ahead and quote your own post back at you.
Let's look at the ranked must haves:
Juggernaut Tank (Melee)
Assassin Tank (Melee)
Carnage Marauder DPS (Melee)
And because of current state of smashspec, having it on top of the above doesn't hurt:
Smash Warrior DPS (Melee)
So, excluding healers, 4/6 (tank + dps) are melee. the other two could be PT/Sniper/Sorc. The PT will be with those melee, and Sniper has no problems being close to them.
What I mean, is that the game is heavily gimped towards melee, and zerging. So no, I'm not seeing bubble spec as a bad thing.
wat no merc?
