I really don't get the whole purpose of it, honestly...
I'm like OP where if I had to go away from my Playstation, I just brought the controller with me and pressed a button when I heard it ding. The only time I went away with the controller though was with PvP or some of the CT/ST raids so I could afford to be afk on my rush back to the room.

I'd be down for it to be defaulted to "Yes" rather than a weird Wait that just kinda hurts the situation. Lemme press Wait, which is the same as pushing nothing at all...
