As for ret paladins, removing or significantly reducing the cooldown on Turn Evil would let a ret pally chain fear undead or demons, without giving the same functionality to a prot paladin (who doesn't want to be hard-casting spells while tanking) or a holy paladin (who doesn't want to be chasing a mob around fearing it while he's the group's sole healer). Without knowing what WotLK dungeons are going to look like though, there's no way to say if a CC that works on undead/demons only would be enough to make ret a decent 5-man spec.

Or, who knows, maybe I'm being overly optimistic. After seeing Magister's Terrace I don't expect much in terms of heroic class balancing. "Hey guys, we made an encounter with 5 untankable mobs that can two-shot your healer and can be completely removed from the fight by polymorph! Our tank/healer/magex3 playtest group said it was awesome!" /facepalm
