Riot please, when are you going to fully uphold the Summoner Code?
Refusing To Communicate, Perhaps not for not talking a lot in game but two behavior issues that need to be looked at, instead of just dealing with false reports by your automated systems, and chat toxicity in game.
1.) Players who do not talk in champion select, This happens a huge percent of my games even when I am first pick, I ask the team "What is the team composition" "What Champions are you all playing in this game" You get Zero answers, especially when and if I am playing a bottom lane role as a support which can have a huge impact on a game played correctly when specific champions are picked around a team correctly, or which can result in feeding a bot lane due to no communication if either player has no idea what they are doing.
2.) The players who don't listen when a player who has pick order is called a troll by their team and told to go play (X) Location after being said by (X) player in chat they are not playing at X Location.
3.) Junglers who just run in peoples lanes and intentionally get themselves, or their mates killed despite a lane that was going well before they showed up, this is the biggest in game communication issue I personally experience, common sense.
Your lane you are ganking.
. The enemy is at full health . Your teammate does not have any skill that can bind or slow down the enemy . You played something like Riven Jungle
But you just run into the lane without typing into chat what the plan is, or letting your lane player call it especially when the champion you are playing is not listed as a jungler, or an assassin and you do not think there is a chance to get a secured kill you should always confirm this first, or type into chat you are just going in to damage the enemy.
Bottom Line I find no excuse for the ignorance of others in games just ruining games with toxicity because they can't talk at champion select when a clear question is asked, "The Summoners Code" Should be upheld starting here at least at champion select when it comes to refusing to communicate, and reports filed.
