In PVP, I never bothered with VT/VE. Things die too fast. Non-epiced classes typically die in one mind-blast/mind-flay cycle (900x4 + 1200x4 = ~8000HPs = D.E.D.). Bout like fireball+fireblast on 4 mages, but not many people walk around in shadow resist gear, unlike fire resist gear. Destro locks with that immunity to fire/shadow talent were the real problem ones as all the shadow shit I'm shooting at them would trigger it all the damn time.
