Of course level 35 players won't receive same points as higher levels. Because you can kill map2 metins with weak equips/skills but you need much better things for level 70/85/90 metins.
Plus there are 4x3 metins spawning each 30 mins at Infernal Flame Field. And how many stones for map2? There are 3 kingdoms of map2 too.
I think this is balanced and fair.
