I know this should be common sense but a lot of people don’t seem to catch that the next match is going to start soon and that they don’t have to leave the map. Sometimes people leave the half of a Stopwatch match. My suggestion is simply to make a UI change where something like, “Next Half/Map starts in X seconds” in the very center of the screen. And shortening the amount of time it takes to get to the next map would also help a bit.
A couple of my friends who play almost always left because they didn’t notice the off-center grey lettering that states when the next match/side takes place and they have simply been returning to menu.
