Ever have someone ban your champ in NORMAL draft pick to try and get you to dodge?

Had it where someone wanted to me to switch roles with them, I qued top and bot, but the whole reason I even decided to play a normal round was so that I get to play the role that I want and practice. Im all for switching, but I honestly was not in the mood to play adc bot lane. I told them no (apparently they were a three man group) and they all started freaking out in chat. Finally the last ban gets chosen, and one of them decided to ban the champ I had selected.

Makes me aggravated how annoying people can be some times. I also kinda wish Riot added a way so that people can que for just one role. I get we aren't getting team builder back, but whats the harm in someone queing as ONLY mid, this way that player is guaranteed their role (whats the negative? longer wait times? most people I know would be willing to put up with a longer que in exchange for getting their role of choice. at least at this to normal mode, where most players go to play a certain role based on what they feel like having fun with, and usually have a champ in mind they want to play.

If this feature would be implemented, gone would be me getting a role I want and someone being pissed they got their second choice and them harassing me into switching with them by having their group ban my champs.
