U don't have to leash the mobs if you straight tank the vanguard, sleep the elites and pick them off one by one guys. Our ls did this last night for a couple hours, tho we did overlook it at the beginning. Also, the reason you guys might be confusing the killshot for who has claim is because when you leash the mobs they could be deaggroin right before a kill and your killshot could be for claim because i noticed it happening last night before we were straight tanking.
