Does it happen that you accidentally queue for a battleground alone instead of as a group when you are the party leader?
If yes, this might be the solution for you.
Disables the "join" button if you are the party leader (but of course, keeps the "join as group" button enabled).
I love you! So many times I've had to eat that deserter debuff, ruining a night of battlegrounds with friends.... UNTIL NOW
