Honestly a few cheaters in a game is way less of a problem than letting a company, especially one owned by tencent, have root access to my pc. Anyway in my experience with league the cheaters are either mostly nonexistent or subtle enough that it doesn't impact the games. Also nobody in here's going to have a rank that's actually important and I don't see why they can't have the fun anticheat in tournaments and ranked but leave it out of the other things.
