Champion Select for Blind Normals
I have been playing a lot of blind picks lately and I've noticed the position calling is really left to the players to decide in a very up in the air sort of fashion that can lead to trolling and conflicts.
I think a good alternative would be to wait until everybody connects to the lobby (timeout late connectors after x seconds) and then players can click a position they want, similar to team builder but more on the fly. If two players pick the same position it could 'roll dice' to see who wins or something. This could just be a guideline and if people still want to troll pick they could, but it would be a more solid way of picking positions and I think it's reasonable and easy to code. Just a thought.
This is at least better than seeing who can type fastest and hoping nobody troll picks your call.
