@melanol removing the 4v4 no share queue was a good idea I think, since having multiple very similar queues will split up people between the queues which is bad. Even if you can technically queue for both at the same time, there are a number of scenarios where people wouldn't do so since they clearly prefer one over the other.
But adding queues for the most popular (even if most contributing members don't like them) maps should be done, since anything that brings people from the matchmaking tab to the custom games tab is especially bad for new players, because "just host yourself" is not an option for them, so they have to put up with all the shit going on, plus you can only be in one lobby at a time, so you are forced to play what fills fastest, instead of trying to get a game in the mode you want to play.
