Seeing alot more summoners leave lately.. If you're planning to leave could you leave a reason why?

I've lost over half my friends list ( Which is pretty large btw consisting of over 200ish friends ) And I've noticed a large sum of them no longer play league ( Now I have to do a purge of my list ) And these are people who in s5 ( When I joined league ) only had positive things to say about the game I learned from some of these people and befriended some of them I met these people as I leveled up to 30 and some I met during ranked games

Yet now I'm seeing a lot of them leave ( Started a month or so ago )

Just wondering for anyone that's planning on hanging up the cloak if you could provide a reason ( Other then " Riot doesn't listen " or " The game lacks new content " ?

Just feel like I'm missing something here ( Maybe a really good game just came out or something like that ? )

If you don't feel like commenting that's fine I'm just curious as to where all my fellow summoners are disappearing to..
