In regards to positions

I don't know about you, but I'm tired of wanting to play, say, mid lane, and someone else calls it, and picks out a mid champion before I can, forcing me to go somewhere else, or fight them over it. So, why not try out the following? Put in a choice when in solo/duo queue where I can pick from a drop-down menu for choosing role? Like, imagine it this way: I hit solo queue, and am given an option for my role, maybe check-boxes for roles I can play. Top, Jungle, Mid, ADC, Support. Then, I get teamed up with people based on what I chose. So, if I picked Support and Top, I would get matched with someone who picked ADC, Mid, Jungle, and either Support or Top. That way, people get the roles they want and there's less fighting in the pre-game lobby over roles.
