Never said that alliance is NOT doing it at all. It's your idiotism that said that. And I'm 100% sure, since one of my friends is playing horde, that horde players are doing it MORE then us. (it's quite known fact.. I mean, even on this server and on many, many other during the past 10 years, I've witnessed horde doing it more and in a more pathetic way then the alliance).
Anyway, @Aunstic, I assume you're one of those gankers, since you even sound like one. And each one of you, before killing lowbies, have in mind that you're farming "honourable kills" - there's no honor in killing lowbies..
