That's assuming it doesnt get resisted in the first place. That's also assuming he isn't a blacksmith. And he isn't undead. And he doesn't PvP. And he . . erm . . well you get the point.
He is a Orc, in pvp he will not be fighting undeads. I can't remember anytime where my warrior resisted a seduce. I used to duel against a warlock a lot when I was playing wow and I could never get near the bugger and he did massive damage.
