I guess the main question is which one first. PLD seems, from the sounds of it, is currently quite a bit better than DRK in terms of general mitigation and overall raid utility as OT. Since I've only got one shot at the MSQ (and the experience that comes with it) I'm just wondering whether to push for the several million XP for 55-60 on DRK and face the full 50-60 grind as PLD, or do the 50-55 grind as PLD, switch to PLD for now so that I have a stable and (to an extent) "always wanted" tank whilst I'm doing the 55-60 run for DRK.
