A different approach to ranked teambuilder

We all know the pain. Playing ranked, just to get trolled and have someone pick a top laner for ADC because he or she is mad that they didn't get top like they wanted to. But of course, ranked team builder would mean a person can move up to diamond playing their one lane, but have bronze skills in ever other area of the game.

I am suggesting a different system. Ranked teambuilder that lets you pick your lane...but not all the time. For example, if you pick top top top, eventually the game will only let you play ranked as something other than top. So you are going to have to pick a champion for other positions. There should be preferences set where you can pick your 1st and 2nd favorite lane so you play those lanes a little more. So if your preference is top and mid, you will get to play top say, 40 percent of the time, mid 30 percent, and the other 3 positions 30 percent of the time. Or, something like that. You get the idea.

I think this will help curb the trolling and frustration in ranked. Of course, bans would be done blind before the team is revealed and if your champion is banned you would have to pick a different one for that lane. And of course, the whole counter picking part of the game would be gone.

This is a very rough idea, but what do you think?
