An idea to help make league more balanced

I was playing a game and I found that when I used the ping system, it often didn't have quite the effect I was looking for. For instance, if I sense a situation where my team is greeding, and I ping them to retreat, they in fact do not fall back, and instead end up wiping.

I suggest that I be allowed to override the keyboard and mouse inputs of my teammates to completely lock them out of the game. Essentially I would control their champions the same way I would Tibbers, Morde Ult, etc. This way, if the ping system malfunctions again, there's a backup plan in place that eliminates the possibility of someone making a mistake that they're being told their about to make.

Sorta like how some cars have a rear view screen showing you shit that you're about to hit as you back up...but if you continue to back up, it puts the brakes on for you.
