Banning teammate's champ
Why do so many people feel that it's okay to ban someone's not troll pick champ? Okay, if someone wants to play Amumu ADC, you might be justified to do so, but I just had someone ban Raka on me because: "Jhin can heal himself, and Raka has no cc". -_- Don't ban your teammates' champs that aren't troll picks. It's extremely tilting. If you want them to play something else, just ask them. Chances are, if you force them to play a certain champ, it could be their fifth time playing it, which could effectively lose you the game. There's also a chance that the other person could just pick something like AP Vayne, or Yasuo support.
