If things stay the way they currently are I'd imagine we'd actually see a PLD/PLD meta comp, as they currently offer the highest damage and the highest mitigation. The only caveat would be if DRK really did Soul Survivor's PVP bonus added to the PVE skill, in which case PLD/DRK would be the way to go. WAR really doesn't offer much aside from better CDs, but that can be circumvented. That said, DRK doesn't offer much either since Blackest Night comes at the cost of DPS potential. Hopefully they do some number adjustments before release, though.
