DK/Healer won't work well - no mana drain, no MS effect.
I can't really agree with that. The entire Unholy tree is practically hand-crafted to kill Resto Druids, and while the Blood tree lacks an MS effect, with all the self-healing talents in the tree it's not at all unreasonable to think that if it's a battle of attrition and not a race to a quick nuke-kill that a Blood-specced Death Knight will be practically unkillable by any other melee and so run their healer OOM.
Spellcasters are a different story, but caster/healer 2v2 typically doesn't work with anything outside of a Warlock, unless you count a Hunter as a caster.
As a whole though, still, I think DK's will fit more into DPSx2 teams in 2v2, but with the right healer and right spec against certain opponents, it'll work. Can't win 'em all in 2v2, the team set-up has more to do with your win here than in any other bracket. What'll matter is how many combinations you can win once all is said in done, which nobody really has a clue about and won't until DK's get figured-out, assessed, abused, rebalanced (you know it's inevitable) and filter into the arenas at 80.
