Afkdingers in Coop vs AI

Hello there, Recently I have been playing coop vs AI (because i had to levelup an account) and I faced the legendary afk heimerdinger in coop vs AI. For those who don't know, it's about placing yourself behind the krug camp's wall , putting a turret there and "controlwarding" the camp, so the turret keeps attacking it. What makes it an issue is that it makes heimerdinger bypass LeaveBuster system, so he can stand there afk and kind of ruin the fun of a coop vs AI. Even though it's not a "real game", it's still frustrating to lane 1v2 especially when you are a beginner, and it's pretty toxic. I have a few ideas to fix that :

• Make heimerdinger turrets no longer bypass the leavebuster
• Make heimerdinger turrets don't attack through walls
• Fix the leavebuster and make it happen earlier so you can kill the camp and make him leave to be in a fait 4v4

What do you think ?
