Be honest Riot. Do you want people to play your game or you to play your players?
I recently heard that that Riot has issued a possible ban for the highest rated mastery Singed player. What he is known for is grabbing smite, killing the initial enemy jungler at the start of game, and then going bot to support as Singed.
To Riot, they believe that if the overall players playing on one's team doesn't enjoy something you do, then it shouldn't be happening and therefore bannable.
To the player, they believe that if the overall player trying it is trying to win, it isn't bannable. AKA purposeful trolling and feeding is bannable.
This is an obvious disconnection between the player and the almighty Riot. If RIOT BELIEVES THAT GOING OFFMETA CONSTITUTES A BAN, they are seriously lying to the player, for what they say is bannable isn't what they will be banning.
I have a badge calling me for being an Honorable Opponent, that I have lost and regain several times on my player. I play offmeta, and for the main part, everyone enjoys my company for being genuinely kind. What I have learned is that making it normal to play meta is the very reason people are toxic at all within the meta. What I see is people complaining "oh you shouldn't be that. It doesn't work. F you. Your mother die. ect" and that is half of the reason people are toxic. The second thing I see is people saying "oh you suck. delete the game. 0/4 well F you". People focus too much on gameplay, too much on the meta, and by doing these things they become toxic and unfun to everyone else.
Riot. If people don't like playing your game, you don't ban the people they blame for it. You get rid of the reasons people are actually upset: an over-focus on the meta and playing well.
