I'm still committed to the human guardian along with the rest of my lineup, but the mesmer proved not to be as fun as I thought it would. Blasphemy, I know. I might make a thief instead (without knowing too much about the profession) if only to reserve a single-word name that I suspect would be in high demand.
Granted, that was my fourth or fifth alt; guardian, elementalist, and even engineer met or exceeded my expectations, and I doubt the necromancer will disappoint.
More character slots. All my gems.
