Druids and Shammys are the best healers right now. Followed by Pally and Holy Priest tier 2 and Disc Priest and Mistweaver tier 3.
In PVP they're all pretty good except for Holy Priests. Mistweavers and Druids are probably best though with Disc wrecking shit in arenas.
lol you gotta actually learn about your players, they'll let you pick up pretty much anybody.
I picked up Marshawn Lynch a couple days ago and have him sitting on my bench just for the fuck of it after the rumors of him maybe coming back in week 5 or 6 started.
I think it was @drunkaholic707...
