Banning nothing is okay
Everyone is getting rowdy on boards about people that ban none
There's nothing wrong with banning none, some people play games for fun, they might want to practice counter matchups, they might be smurfing and not care what they face
The game's balanced, and most of you just need the practice against the champions you ban
People ban <48% w/r trash all the time, that's worse than banning none because you remove the possibility of the enemy team picking a losing team comp
