Teammates should not be allowed to ban pre-selected champions

Hello friends,

I recently queued for a ranked match in solo queue. I received my lane, which was top. To give my team a heads up so we could build synergy, I selected the champion I wished to play which was Nasus.

Needless to say, the first ban a teammate by the name of "Totalwanabe" selected was Nasus.... I could understand at this point if he was trolling, because lets face it without trolls the world would be perfect and that sounds horrible.. but instead, he proceeded to call me a noob, bash my champion select, ,and say that he just saved us from a loss and a feed..

I believe that is unacceptable, as even the worst of champs have value if played correctly, and can carry games in the right hands. This is my recommendation for you Rito, please remove the option for teammates to ban champions that other teammates have selected already. This removes trolling, it removes the options for bad practice among teammates, and it also prevents accidental bans when players aren't paying attention.

Also, do something to this guy "Totalwanabe"...

Thanks!
