Was playing an ARAM just now, the game was really even, both of our nexuses exposed, the final fight would decide everything - all of a sudden, my ms goes to a fixed 500 and I "disconnect". So I exit the client, relog, and try to press the reconnect button as the game was still in progress. The button turned grey, and that somehow disconnected me from chat and shortly after , pvp.net. I relog again, and everything is fine and the game has ended... defeat. I felt like that game could have been won were it not for that random dc. The timing was just ridiculous to be fair.
Any clues on what's going on?
