Yes, i am
I have a good job. I play 1-2h (1-2-3 games / day ) or 3-4h in week-ends. I live with my girlfriend for past 3 years. We have a very good relationship. In my first year of playing LoL (- actually this season - Season 5), i have reached Platinum II from Bronze IV. So i know every ups and downs. I have over 1000+ games already in ranked, since starting to play (November 2014). I am a teamplayer.I am a competitive player in every game i have played. When no one trolls my game, i almost always receive Friendly/Helpful/Teamwork honor from my teammates (or honorable opponent). When some one starts trolling, i get toxic. I don't like bad players. I actually dislike them. That makes me toxic. Eliminate trolling potential, and you will have a less toxic environment.
But, until then, I am a toxic player. Help me.
