How about every week you get 1 xtal/1M CS that you DON'T have? Up to 5M CS. This would help smaller players get a boost up, while larger player won't get anything. That would help narrow any gap, rather than widen it.
So 2 for every 50K stats? That means I would receive about 120 Xtals XD (Delphin's idea sounds promising tho )
Ok i wasnt thinking about all of the things that would happen to devs or anything. So forget about this forum cuz its is a terrible idea. Srry
