Not sure if I understand you stealthy, how would resilience cause war stomp (or any stun) to resist? War Stomp does resist frequently though like all active racial abilities. I can't count how many times my blood elf paladin's arcane torrent resisted when I needed it most. Too bad engineers can't use bombs in arena =/

I have two orcs (hunter & warlock) and the passive stun resist is hardly noticeable. I'm more hard pressed to give up Blood Fury. I think at the end I'll go for looks / armor skins.
