Horde logging out while being attacked in IF

My server has a horde rogue in the city basically 24/7. Whenever this guy is about to die he just disappears completely, same with a horde warrior that hangs around. It’s bad enough that Ironforge basically doesn’t have guards so horde can just walk right in, but you can’t even kill them half the time because they can literally log out in the middle of getting killed.

heyhey-
I go to IF all night long, but what I do before I go there is Q for AV. if my AV pops , I try to kill someone before entering.
I can enter the battle at any given time, so if there is a lot on me, I will take the Q.
does this help clear things up?

That’s not what they’re doing though. Last night I switched to a horde alt right after it happened and the guy was in org. Literally a minute after I switched back to my main he was somehow back in if killing people.
Hes done it multiple times within a span of 5-10 minutes.

You use the “stuck in the option” and rez right before it activates. It will act as a free instant hearthstone. Is this what is happening?
