Barman Bill

If you're ranged, he can be pulled alone, and just back up to where you won' t have any pats walking up to you. If you have a pet, make sure you put them on passive before trying to pull him. He will take his time getting to you (walk of over confidence I think) so you'll have plenty of time to put your pet on assist before he gets to you.

The hassle of this quest, for the reward, it's really NOT worth doing unless you're in a group. He's not that difficult to take down, but the possibility of all those adds, can make in an impossible quest very quickly. I received 4 Gold, 5 Silver and 53 Copper, 47 Artifact Power to my Heart of Azeroth and a [item=163717], which sells for a whoppin' 10 silver. All in all, it's just really not worth the amount of trouble that is a real possibility that you'd find yourself in. I'm a hunter, and had to Feign Death to avoid dying the first time as I forgot to put my pet on passive, he pulled EVERYBODY. If you're melee, good luck doing this solo, unless you're geared out the hind end.
