The problem with others playing while high/intoxicated
It's extremely unfortunate that people feel the need to massacre their brains in order to find temporary pleasure, but that's their decision. It becomes a problem when you force me to have to put up with your terrible life choices. Specifically in ranked, where I get punished for you playing as high as a kite or completely hammered, it's unfair, unpleasant, uncouth and untoward. I don't enjoy it when people play that way in normals, but it's utterly inexcusable in ranked. Yet I have never seen any sort of action or Riot statement or anything about it, and I encounter it enough for it not to just be one unfortunate and isolated incident.
Please make playing this way (and blatantly admitting it!) a bannable offense (at least in ranked).
And please, for the love of all that is holy, stop playing this game when hammered and high.
