When you are in battle make it so clicking on the map clicks through it for 10 seconds or when within a certain distance of a visible champ. Cant tell ya how many times i have been killed because of maps.
When an ally is fighting an enemy champ disable surrender. Nothing worse than someone dying and giving up and deciding to bring a damn popup right into the middle of your screen.
make it so allies cannot ban highlighted champs. Seriously, you ban my shit I'm gonna gonna feed your lane. Lets avoid that shall we.
Outside of game a disable allied chat option would be nice. You are having a bad day and have low tolerance for stupid bullshit? Enable disable allied chat so you don't risk saying anything. Make sure it is not possible to re enable in game tho. No one has the ability to always remain in control of themselves 100 percent of the time.
