I think League should do a small test on the User before Queue to check performance
^ so title run a quick check and have a minimal requirement if it's not met person cannot queue until they fix this. I don't think people with sour net or just over heating laptop/PC want to be banned for that and their team mates shouldn't suffer because of it.
Like honestly if your set up can't handle it go play runescape ¯_(ツ)_/¯
