I have played 3 battlegrounds today - All of which started with multiple people starting the conversation with “If you die, Alt+F4 to resurrect”.
I thought this was a joke, but when half our team was dead and no one could revive, and then I died and could not see a spirit healer, it made sense.
Horde Players are unable to revive unless they re-open the WoW client. Upon using Alt+F4 I logged back in and appeared alive in the BG. This is killing entire BGs and wasting 10-20 minutes of time. The winners have no one to fight and the losers have to exit the game to have a chance. Alliance is not having this issue and they are currently taking advantage of it.
