There are people out there that probably haven’t run in a PUG…well, heck, maybe ever. They would rather not run a dungeon than chance the inadequacies of the random player. Not to defend the PUG, but I PUG nearly everything and find that 90%+ of my groups are successful with little or no real player error. And if there is it’s usually not a totally big deal.
I suppose that being the healer and having a little more control over the group helps as well. I’m now to a point again where I am comfortable healing and even able to pull off some pretty awesome group saves.
But there is one other reason that I PUG a lot on my healers. And that reason is Call to Arms: Healer. I won’t try to convince you any other way, than with pictures.
