For me it's arenas, I enjoy the others. More and more arenas keep popping during prime time (DM server), sorry but I don't enjoy them and won't play them anymore, so I leave the match and can't queue again on any character for a while. If there's nothing else I want to do in game, I just log out and rarely log back in that day. Your suggestion would help me to play the game when I want, in the way I want, without impacting other players through leaving.
