Why is this acceptable by the community? Its outright unsportsmanship conduct
I'm talking about players picking a champion for the first time in ranked or when they don't even have 10 games with that champion. There is a mode called normals where players can play champions they are learning and so they can bring them to ranked and don't try them in ranked and RUIN other players games just because you felt like trying a champ or just because you recently played a game or two in normals you think that's enough for you to bring it to a ranked game when its not.
I just had a game where our mid Galio went 1/9 with 7k gold and 110 CS in a 30 minute game, silver elo. Even for silver elo that's very poor stats, believe it or not, so I checked this guys op.gg and surprise surprise this guy has 5 games with Galio in season 8, and this was hes 1st game with galio this season.
With only 5 games on Galio VS a lvl 5 mastery Cassiopeia no wonder he got fucking destroyed in the lane. And the rest of us have to put up with this? why? why is it acceptable by the community for players to be doing this in ranked and literally made 4 players lose or have a huge chance of losing just because you feel like playing a champion you more than clearly don't know how to use decently.
