How good is Tinkering? Enough to go Gnome for Necro?

[VincentVolaju]

So I'm going to try out a Necro and am undecided on whether to go Gnome, Dark Elf, or Erudite.

So far I am leaning towards Gnome because of Tinkering, but not sure if that's enough reason to go Gnome over the other races?

Dark Elf look the coolest imo, and get hide (not sure how good that is?). Erudite has the highest starting Int, and like mentioned, Gnomes get Tinkering.

Is there anything I am missing?

What race did some of you guys choose for your Necro, and what made you choose that race?

Thanks!
