Yeah there is, all I do is /mute all at the start of a game, it honnestly helps.

Returned to league after a few months off, was based at plat 4/5 elo, however i am now in gold 2. I understand im rusty but i mean come on.

Few months actually might be enough to lost a lot of ability. Especially if you're not on the pc or watching professional LoL.
