Gnomish Cloaking Device u can use/make before u choose ether gnome or goblin

If u are a pally then i  would go with goblin, because u have a way to pull mobs and have some aoes

but if u are a high dps or long distance class i would go with gnome because of trinkets, and the net is good to keep them away (or right next to u if it catches u)

and the death ray is good with warlocks because of high stamina
