Don’t know if anyone has mentioned yet but why not just use ro’s rebirth system. The level cap can be 100 and each rebirth just makes it harder. The total amount of rebirth would be 6, so same as tos’ intended cap of 600
To deal with changes to the leveling system mobs will also have a cap of 100. Any mobs that were higher than 100 would have a star to denote their strength. Eg: level 230 mob would be level 30 with 2 stars.
This way the level range is a lot smaller making it easier to level.
There may be some issues with power leveling this way do maybe they could implement a penalty for lower leveled players if they try to hit higher level mobs. Eg: a 2 star mob only gives full xp to players who are on their second rebirth and above. Monsters lower leveled than the player still give players full xp, allowing them to party with their lower leveled friends, only that they get less xp
