I've noticed that my search bar is almost always full, and I usually have to wait 3-8 minutes for a game, even during prime time. And with a full search bar, it's all but guaranteed someone's gonna have an idiot/feeder on their team, and they seem to nearly always either not speak English or be muted.
No idea what that means, but it's definitely making Dota less and less attractive as a use of free time.
