This has been ongoing for months, yet they really need to correct this.
She respawns if you kill her too fast, and she shouldn't. This is more obvious on Normal Queue's, but also happens on Advanced quite often, can even occur in Elite queues.
Here's what she does (respawns) and doesn't recognize her own defeat. The annoying part, is most of the party gets AFK penalty even though they aren't, simply because they have no way to defeat her at this point. Waiting for the timer to cycle doesn't often avoid AFK either.@ambassadorkael#6946
