YOU'LL BE BACK!!!!
Probably not... I'm working this summer.
Then why did you reinstall it?
As for healing? I don't measure a healers worth by how MUCH they heal. (Maybe in raiding, but... It usually, in my experience, means they're just pulling more weight that other healers SHOULD be. Not that they're necessarily any deal better.) It's the sticky situations, the crazy bosses, and long ass fights that make or break a healer. And, honest to god? It's nothing special if a healer can do it. It's a matter of knowing your class. There's just so many BAD healers out there that it's recognized when you actually find one that is able to heal through the tough times.
Tanks are pretty much the same. It's really all just a matter of knowing your class, and your role. As a druid? If I tank, I never lose aggro. If I DPS, the #1 spot is reserved for me. If I heal, I keep everyone alive. I battle res on bossfights when a tank or healer dies, and innervate the silly healer that can't reserve their mana, or if the fight just goes insanely long. Would I consider myself good? Sometimes, yes. But honestly? The only reason I'm in any way better is because
a majority of the game is just so goddamn terrible. Once you hit 70, that's when you'll really know. Though, I've only seen one paladin ever heal successfully for a five man (at 70). It's not because they can't. It's because most of the paladins I run into.. suck.
EDIT: Probably a dead issue, but, my two cents.
