Kill Counters

I think it would be cool if there were kill counters tagged with each skin, or a way to attach a kill counter to a specific skin. Much like a stat-track from CS:GO. I'm not a CS:GO fan by any means, but I do think the idea of having something count the amount of kills you have or the amount of assists you have would be really neat. Then you could show off exactly how skilled/seasoned you are with a specific champ, with numbers. The number could even be shown in the loading screen kind of like honor or champ masteries. Thoughts? The only issue I see with this being Valve owning a patent on the concept of kill counters. I know ideas like this can be patented, so if they do own something like that, then I'll just have to keep dreaming.
