Well, Enha counter Retris, but still Retris are stronger than Enha in the general =p
I think a Frost DK should be up there with boomkin/fire mages/affliction locks for dot damage in rbgs.

Warlocks are a hard class to play, same as any other class if played at high level. Yes, some are more easy to understand while other takes more practice but at the end it becomes easy. I hate when people say "Frost is the best spec" or " Fire is the best spec" and same goes for every other class. For example,FROST mages bring more cc with a longer duration while FIRE bring cc in a short duration.
Let me mention something that hasn't been mentioned in here : Prot warrior are amazing in rated bgs.
Also every class is great, it all depends on how you play it. I've seen many warriors either in bgs or arenas or world pvp. They never Intervene healers or heroic leap into trap so the healer doesn't eat it after scatter. The same goes for mages, they never blink into trap to prevent the healer from getting stuck in it.
