Owning a noob once teaches them a lesson. Camping them makes you look like a noob and teaches them that you (and the horde in general, as a noob getting a first inpression) have no dignity or honor... I bet him and the moonkin sat on YOUR face too :|
Naw, though it would have been funny if they did. I don't mind if the "newbie" got the impression that the Horde are all "noobs" because of me, and I don't care if he thinks the horde have no dignity or honor. If he wants to form a shallow, immature impression of the opposing faction in a videogame, he can go right ahead.
I personally love PvP and get a kick out of it even when I'm on the reciving end. Unfortunately I don't have any good stories at the moment.
