I have a proposal regarding the global rating system.
I am playing FAF for the last 3-4 years with periods of stoppages. The longest one was in 2021 for almost 9 months.
Of course when you are out for so long time, your gameplay level is suffering from that. And if you are 1k+ rating, when you came back, you are pushed to play with the similar number, because noobs is not willing to take you with them, and basically you are frustrating yourself, frustrating your teammates, as you are not playing on the rating level what is supposed from you.
My personal example, that my previous stop was in 1.4k rating player, and stopped for 11 months for personal reason, came back in beginning of 2021, and then i was obliged to create new account.
So the general proposal - that for every 1 inactive month you loose 100 rating or 200, whatever is balanced up to the level of 0, so if you are out, you can restart your gameplay.
