I have a level 57 paladin that just tanked Upper Blackrock Spire without a healer. A moonkin placed the odd rejuvenation on me, but otherwise it was still pretty easy just with word of glory and divine protection. Nobody came even close to dying, there was one mana break, I only popped two flash heals on myself (apart from Word of Glory) and that was after fights.
I would just like to hear people's opinions on whether we should we be able to do that? What do people think? Personally I think that a skilled group should be able to four man. But it should be a lot harder than it was. I mean, am I going to roll a healer now that I've seen what I've just seen?
P.S. Sorry, I'm not sure what unning is either.
