Invasion event

I've actually asked people for specific comps, and when they refuse to, i ask to FF in game, and for some reason i can get reported for that since i don't wanna waste anyone's time because i'm not playing for anything less than an A rank? I did the math and shit to realize that some comps just won't work. I give it a try, for the first round and when we die and get like a C rank or something I just like legit just stop playing because at that point they're just trolling me. I ended up being reported for them trolling me and being selfish and actually getting a chat restriction for something? Riot can you please not support the butthurt normies in life?
