It's certainly handy but luckily you had melee's to even use Bloodbath. BLM and even SMN would be in a pickle other than Second Wind, same as anyone in the Physical Ranged space. Pots aren't also the most helpful things compared to a Clemency or Nascent Flash.
It's just unfortunate that Valknut still speaks true a bit in that DRK is just a bit off point for dungeons compared to the others. Sure, DRK can work some magic but it's a little more tricky than usual, that much is for sure. It's a preference thing though I suppose.
