I would like to propose a new feature related to the rating of every user, maybe it could help to not have rating inflation, which is a topic some people complained about. Feel free to comment if you like it or not.
There are many people here in this community that stop taking part into contest after reaching some goal, me included, which is fine, although a little bit unfair if you think about other people still taking part into contests.
If you have ever played a very competitive game, like League of Legends (LoL), after you reach some spot (like high rating), you need to keep playing, otherwise your raking (rating) will automatically decrease.
I don't know how much rating and amount of time would be fair to analyze. Something like, you lose 1% of your current rating every month that you have no participation in contests. I know there are not many contests for Division 1, it could be a little bit more flexible, keeping track if you took part into any of the last 10 contests, for example.
If I'm not mistaken, as you keep growing your ranks in LoL, this feature is even more harsh, it would require you to play every week, otherwise you will lose points.
What do you think about it?
