Team BANNING CHAMPS

So i think riot should implement a system where if I declare a champ , my team isnt allowed to ban that specific champion. AND the enemy always says , oh you have a 33% winrate , i dont want you to pick him .. '' WTF IS THAT garbage. i declared the champ and this guy BANS IT, douche. THIS needs to stop (insert meme) . RIOT please block teambanning. if i declare a champ i expect to play that champ. THE WORST IS WHEN I PICK YASUO THO . MY TEAM bans YASUO because they say '' hes a hit or miss champ '' '' i dont want to risk it '' . or even'' yasuo mains'' . ik it may be a minor problem but its not a joke . really kills the game when they deny me my favourite champ because of a stupid winrate.
