Pulling everything is a bad idea unless you're sure everyone else is a good guy (and thus will back off from your territory). This is because the ability to tag anything is limited to 1 per GCD (mobs generally are way too spaced out to tag them with AEs), so if you get someone angry enough, you basically end up splitting the camp which is likely not what you intended. As is true in most prisonner's dilemma scenario, the optimal strategy is start off being a nice guy and then switch to being a jerk if anyone dared to cross you.
