I'm afraid to indicate who I want to play in Dynamic Queue
Players can ban who I want to play to be jerks (which has happened many times before). Also, if I want to trade one of my teammates a first pick (like jax or dr. mundo), then I'm forced to reveal to the enemy who I want to play before I can choose the champion to trade. If anything, I've been using it to trick the enemy. If I'm going mid, and I want to play Lulu or Morgana, then I purposely choose Soraka or Janna or Taric to make them think I'm support. I don't think this is what Riot was intending when they decided people should declare who they want to play.
Just an idea, but I don't think the enemy team ever needs to see who you intend to play. Maybe, fix that?
Love,
Support
