Keep playing WoW and your ass will get fat.
I've played WoW for over a year and my ass has stayed fine, thanks.
@ Furious, that's pretty awesome.
I tend to be pretty impressed of Paladin healers, because I usually run into very few that are actually anywhere near decent. Good healers are hard to find.
Have fun when you get into Kara, though. Second time I was there with my current guild, we accidently pulled two groups and some dufus accidently pulled the first boss, Attuneman, too; We took care of the whole thing and the healers didn't even hit half mana. While you'll probably always feel awesome yourself, its an even better feeling to realize that the people you associate with are just as awesome.
