Automatically Calling Role(s)

It would be nice if in ranked, Riot would have you fill out a little form with which roles you want to play and then present that to the team in a grid. This would do nothing else (i.e. listing 'mid' here doesn't guarantee you a damn thing, it's purely informational).

The point behind this would be to help people find the optimal roles. If you only have one person who plays jungle, well, it would be really nice if they were the jungler, etc. And with the fact that some people never type (until AFTER picks are done) this could bring a small amount of coordination to solo queue.

So, to recap, it would simply give us a grid like this (but nicer looking) and would not force anyone into any role, it would just serve as a replacement for calling out roles at the start of every match. It would also be required, so everyone would know what you can play (i.e. no more "but I can only mid!" types). And you can, of course, say that you intend to fill by clicking all the roles. It wouldn't force anyone to do whatever and if people wanted some weird troll lane, they could just ignore whatever it said.

But for everyone else, it would help teams spot when they only have one competent support or jungler or whatever and hopefully reduce conflict with the people who never say anything about roles until it's too late, because it would force them to communicate ahead of time.
