This is ridiculous I only get disconnected but only when I am playing RANKED games and oftentimes right as I am about to win or during round 1. I have been playing casual all day, come into ranked, Get disconnected in 3/4 of the games. I have stopped playing Ranked because my MMR has tanked because of this. My computer can handle games that are infinitely more taxing, there needs to be a buffering/ timetable if your computer starts to lag or at least if it doesn't get fixed make it so you don't lose MMR...
