Gaslighting

It needs to be addressed. Where someone can continually harass one person til they explode and they are made out to be the bad guy.

There is full information on this link. I guess you could report for griefing but I'd actually give the option for gaslighting. You always get that one guy who can't let it go and continually berates you and then you get fed up with being abused. People have a right to defend themselves regardless of what Riot thinks. You get tired of feeling inferior for one simple mistake and you explode which helps the gaslighter turn teammates against you. This seriously needs to be addressed in this game. People make mistakes. Deal with it.
