Guild Wars 2

I have seen plenty times while im leveling in orr an event pop up. Now in my perspective, the answer to most of these is kill everything. So whats with people calling people dumb or stupid for not luring one npc to another? Its usually a champion or veteran mob that some want lured to a pact npc – and this does what? Another one I dont get is the one in the centaur land. The guy summons two huge earth golem hands and people say not to kill it. Once again I ask: what does this do? Are these exploits of some sort like the risen giant grubs? Better loot?

It fixes the damn bugged Balthasar event which has been broken since release. The southern escort team gets bugged notoriously often and the event chain only progresses if you wipe it.
