"Intentional Feeding" and "Assisting Enemy Team" don't cover it for griefing. They don't even start. I can't remember the last time I accused someone of either. You know what does happen every single day? Inhibiting allied team. Hell, didn't some streamer (stonewall? some jungler) get suspended for doing that? He followed around his jungler and ruined the guy's chances.
Well, that **** happens all the time. Guy doesn't get mid? He'll go to every other lane, stepping on toes and feeding. Guy doesn't like that you pinged? He'll go to the lanes/camps you're farming and try to steal everything. It gets old pretty fast, and because there's no one thing to report them for, sometimes the reports look falsified. Let's change that.
