I wish I was too, but it just doesn't happen for me very often. When I do end up with a meme group, or a undergeared tank, it is very fun, but those moments are so few and far between.
Healers are dependant on other people playing poorely, which isn't great, when Tanks and DPS don't have that problem. It's like I have to pray to the twelve that I get paired with the worst players, so I can enjoy my role.
