Suggestion: Make the Teambuilder queue modifier descale slowly over time.

Just for background info, Teambuilder artificially lowers your expected mmr if you're playing a champion you've never played before on that mode or have only played a few times.

Essentially, my idea is if you spend a long time not playing a champion on Teambuilder, it would tick back from what point you're at, going as far as if you had never played that champion on Teambuilder again after long enough. I think this would be a decent way to get back into the swing of playing a certain champion after having not played them in a while and becoming rusty.
