will my mmr have dropped super low for not playing for like a year?
so I've been a casual player for a long time, I think it was last season or the one before that i even tried out ranked. I did preseason and made silver 4, was pretty happy but when the new season actually began I got silver 3. I wasn't too thrilled about it and decided that I wasn't really interested in play league for much longer anyways so after getting bronze, I decided to leave.
well Im back now, and i've decided to really give ranked a good try. I won I think 6/10 or 4/10 placement games, and got placed in bronze V. I have no problem with this, as I am confident I can climb all the way out of it, but I was just wondering if my MMR actually declines over inactivity. I searched online and they said elo drops but considering I haven't played ranked for so long im not sure if that even applies to someone who occasionally just played normals and hasn't played in well over a year.
Tl;Dr: does mmr drop over time due to inactivity?
