riot creating a more toxic environment

This is personal opinion to make it clear.

I have been playing this game since the end of season 1, i have had my first account banned two years ago and have noticed a serious trend in this community not to say that it wasnt my fault my account was banned because it was, but since the proliferation of permanent bans and increased punishment the game has become less about team work and more about enraging other players to a point where they will be banned with out getting yourself banned. i have been guilty of this, people i play with have been guilty of this, and my first account was the result of the receiving end of this. Since permanent bans have become more common the community has not gotten better in fact i would go as far as to say it has become much worse. I dont think i have played a game in years that was not completely riddled with toxic players. i dont know if any one agrees with this but this is just what i have noticed.
