Team Builder Suggestion: Let people who fill often cut in line
It's really nice that TB already shows what positions need filling, and it's doubly awesome that those positions tend to be what I play. But every once in a while I want to play mid which has gigantic queue times relative to ADC, support, and jungle. I think it would be awesome if people that filled often were rewarded with faster queues for the other roles.
Obviously there's a fairness issue between who mains what. Support mains shouldn't always get faster queues for mid just because they happen to main a "fill role." I think a system akin to the reroll system in ARAMs would work well here. Those who fill often would accumulate points, which they could passively or actively spend when queueing for a lower demand role. Starting a game as a low demand role diminishes those points. More points means faster queue times. That doesn't mean you get to cut ahead of everyone else, but it might mean the matchmaking algorithm takes your points into account when choosing who gets chosen to be put on a team. For captains, captaining a team as a low demand role could mean the matchmaking system takes your points into account when deciding which team to put someone one.
Now all the mid mains out there might be saying "Fuck that. I don't want longer queues than I already have." And you're right that it's unfair just because you like a popular role. I'd love to hear other suggestions on how to make it more fair, but you'd be just as able to gain points by filling.
Thoughts?
