User blog comment:The Lie is a Cake/Would a (public) party system for PvP work in League?/@comment-4952847-20130530061123

I'd only briefly read through but I feel that you're onto something here. It's a great idea for players to be able to specify the roles they want to play as they join a queue, and having a party finder will likely improve the virtually non-existent community as people don't have to get blamed for losing when they got stuck with a role they weren't good at to begin with.

Of course it might be abused such as people specifying support roles to get faster queues and end up picking solo mid... etc., but really if people wanted a faster queue they could just play blind pick or draft.
