Why does LeaverBuster have to work in co-op games too? It seems too unlegit.

LeaverBuster shouldn't be used in bot games because that's the only game mode which are practice games. This game mode is like the only mode where people don't mind if others leave or go afk. i'm pretty sure almost everyone respects that. i mean, these games don't change much of your stats so people don't care and just use them to practice. In that way, they can use the skill and experience they learned in those games to fight in pvp. In my experience, just being afk for less than 5 min already gave me a 20 min waiting time before 5 matchmaking games. It was also just a bot game! I really found that unfair and very dissatisfying. i would understand that if it was in a pvp game because you are facing real people and who knows what would happen in those games. Yet, this was just a bot game! It's insane and I believe that LeaverBuster shouldn't be used in co-op games too and that it's way too serious about bot games. I think Riot should change that in the settings for the LeaverBuster, does anyone agree?
