What he said

I haven't tried blood in PVP yet, but I will. For PVE with a PUG healer or my own lvl 85 holy paladin, they are great. DPS (3-4k atm lvl82) isn't bad and survivability is excellent!

@lvl 82 I did the first boss in the first cata instances without a healer, just 4blood dk, I'm sure I could do more instance content without the healer - but I was simply just testing my setup.

Healer's vary, some get bored and leave because they don't need to do much, some think it's great to watch and a few have equated it to being 'boosted' because we were completing instances so quickly.
