Nah, I didn't play until live.
I may go warrior. I've always been a squishy. I was a Lock in WoW too. From what I've read, Necro will have some tweaks in later patches.
I'm just tired of panicking whenever I pull more than 2 mobs.. Or rather, when my PETS pull more than 2 mobs, then DIE because they DON'T REGENERATE between fights.... AARRRRRGH.
Edit: The Flesh Golem (read puller of all mobs in a 4 mi radius) does regen, but my other 7 pet classes do not.
