I'm not really big into ganking horde while they are questing or anything. If I see something like "South Shore is under attack!" then I usually show up and see what I can do. SS is under attack 24/7 on my server with more horde than alliance. I also got ganked a LOT while leveling different toons, mostly from lvl 70's camping me in Duskwood or something, very rare was it to be ganked by a horde near my level. I guess 70's just get bored sometimes. But, I play on a PVP server and kinda knew what I was getting into.

Sometimes, I even try to help lower levels of opposing factions, and they sic their imp or void walker on me like they are really going to take my group down or something. I don't really understand That, but oh well.
