Should i re-roll?

[Kafter]

I currently have a 40 gnome necro who i love playing based on my current play times but want so badly to be an iksar lol. Do you think it is worth it to start all over? The regen would be another huge reason but mostly just because i love the way they look.

Why didn't i roll one originally you ask? Because when I got this account a long time ago the necro was a gnome at level 30 so i just continued from there!

All opinions welcome! Thanks.
