>>715078919casual mode makes it so that most matches last 3 minutes and then you're forced to vote for a new map, wait out the loading time, then wait out the pre-match timer before you can actually play the game for only another 3 minutes
that is of course if you're lucky and people decided to stay in the match instead of disconnecting at the end because the map vote either had maps they don't want to play or causes the bug where people can't vote normally
quick-play never had these types of problems
