stats/quality scaling to prevent world staleness

[Granger]

I don't necessarily want to deny that this is a problem, but; conversely, if groups A and B are grinding just as hard, but group A has been doing that for twice as long, is it unreasonable that they derive advantages therefrom?

Yes. It's utterly unreasonable for games to be patience contests, because they're supposed to be fun by definition. The thing where you grind for years all day long even though you don't enjoy it is usually called a job.

This.

This is a very scientific graph that shows how stat differences should be handled
