Gnome or Dark Elf Necromancer?

[Xruptor]

So I made a gnome Necromancer (Bertoxx) because I figured a gnome with a huge skeleton pet was hilarious. Not to mention a few other perks like Tinkering. He is currently level 5, but today I had someone tell me that gnome necromancers are absolute trash and I should just rename mine as a Dark Elf because of their 'Hide' ability and faction stuff. I figured being a gnome would make my faction as a necromancer easier? I'm a bit confused here.

Should I just stick it out with the Gnome? or am I gimping myself out and should switch to a Dark Elf since he's really only level 5? Just looking for opinions and or advice. I don't really see that huge of a deal but maybe my character will have issues later? Gnome necromancer seems pretty powerful to me.

What other additional benefits would I get as a DE that I don't have as Gnome?
