Question, the alliance mages in the kirin tor have not be biased? Are you kiding me? Before wotlk they did not even allow blood elves in it in the first place. And to say that none of the kirin tor mages have not helped the allaince(against the horde) is laughable. The sunreavers actions were individual actions, not the whole group itself. Like Artha's purge of Strat was not done by the Paladin order, just some who choosed to take part of it.
There was no time, we still have not fixed the undeath problem. If he would have not killed them they would have died and would have killed so much more. Strat was a big city, I think it was as Stormwind was, would you want all of Stormwind to go undead? Think of the power they would have had if he did not do it.I like to think that in a situation like Stratholme I would try and do everything in my power to cure them rather than just killing everyone after about six seconds consideration. But then again i'm not mentally unbalanced like Arthas so.. Woop.
