If you guys are gonna do this to grind XP, quickest method by far is to set the enemies to vermin only and then camp the elevators on Classified. If you set it to vermin only then you only get dogs spawning, and if you camp in the elevator then they all spawn right in front of you, you can kill them with wall guns and the rounds go by ridiculously fast where the dogs all spawn right in front of you one after the other.
