This is how i normaly do this. I queue for inprogress looking for a 2/4 if it doesnt pop after 3 or 4 times i just take a full run. because then at that point it becomes obv there are no inprogress groups running and its starting to take to long to get in a run. So i do a full one. My goal is to get as many 3rd and 4th boss kills that week untill the piece i need drops and i win the role. So looking for a 2/4 inporgress run is highly effencent for me. This is why this feature exsists. I understand how you feel like it hinders your play but I promise you that your wait time is not inflated because of someone withdrawing. You would still be waiting for a tank to fill that last spot anyways. If there was enough tanks queueing to fill your group you wouldnt get the same guy withdrawing over and over. I am just playing the game with an option and doing it th way it was intended. If you do not like that then i'm sorry but you should just go one with playing the game. instead of coming here complaining over something that is not effecting anyone.
