Some other useful things to know about pulling.
As crazy as it may sound, but mobs do have facing awareness. Quite literally, mobs with their backs turned to you, allow you to get much closer before detection, than when they see you.
What does this have with pulling?
Dont shoot a wanderer when a LT or Boss is staring at him. Honest.
Additionally, its not the attack that sets off the alarm. What happens is that it appears that an "alarm" is generated, at roughly time of impact. LTs have a bigger call than minions, and bosses have the biggest. So when you attack a minion that is close to another minion he will give an alarm, which the other minion may pick up. The alarm pickup distance depends upon facing. If the guy that gives the alarm sends out his distress call, the people that are facing him are more likely to pick it up from further away than the ones who arent.
Short story, pull the guys who wander far away from other minions.
(Interestingly enough, zombies seem to have a reduced distance as it is very easy to yank (or you can pull one zombie away from another when they are much closer together than normal minions)).
Seems obvious, but honestly, it took me a while to figure that out -- I didnt think that kind of detail was in the game.
I dont know the honest to god mechanics of it, I just know it seems to work like that.
