Whenever one method is closed, the gil sellers find other methods of being nuisance. However each and every new restriction, most often to the social functions of the game, gives worse impression and experience to those genuinely interested about the game. While we all agree that gil sellers are a nuisance, I call some responsibility to the existing players as well. To actually read through the dialogs before they agree them.

However, the accepting party invite canceling existing queue status is something that happens at times even in otherway legitimate party invites. I suggest an additional confirmation dialog if your party invite accept would cancel your queue.

"Accepting the party invite will remove you from the queue for duty. Are you sure you want to proceed?"

Possibly even with the new hold yes button. I know some people would click through that too but at least it breaks the normal cycle of click accept and maybe wake up some enough since it's supposed to be rarish occurrence.
