It is bannable , and it definitely is NOT a gray area , why are you even arguing and where you got your weird ideas from ? Didn ' t you read the story of the Signed main who risked a perma ban because he took support and then left the lane to counter Jungle ? If you put your lanes purposedly behind it ' s the highest level of refusal to cooperate with the team , and it is , in fact , bannable . The only way to get away with it is if your laner agrees with your strategy . Here , read this get back to your example with taking some cs to push out a lane , the only reason you can do it is because it ' s a widely known and accepted strategy by most of the community . If you get away from the commonly accepted strategies in a way which has a negative impact on one of your teamates , you need their approval for it . This has been made clear by Riot by now at several instances . And is also kind of normal in a teamoriented game BTW
