I've played wow since may of last year.
I play three different toons.
My main by far is a paladin tank with a dps offspec. I like being the first line of defense to destroy the enemy. I feel so powerful with 8 or 23 ppl behind me.
My alliance alt is a rogue and my horde is a warlock. My God warlocks have shitty survivability by comparison. When I played just paladin, I didn't understand the concept of bandages or potions. They just had no value to me. But now, they're like candy...
