Tricks of the trade as they say.
It's also reasonably fun to tick off a horde char in Gadgetzan. Just go PVP and tease them a little, eventually they will tire and notice that you are a much lower level and decide, arh he's dead. They attack, and instantly they have 20 goblin brutes on their butts.
Don't make the mistake of return their attack, otherwise you'll end up as turtle food as well.
