Suggestion for potential done right

Removing potential isn't the way to fix it because it's obviously too late for that. People have spent hundreds, maybe even thousands, of dollars on cubes and they're not going to be pleased to see all that go down the drain.

Potential is now a big part of the game so IMO all cubes should be accessible through non-NX methods. I don't think dropping from mobs is a good idea because botters will destroy the market.

Perhaps they could implement something like Azwan but for cubes rather than circulators. You earn coins doing whatever and use them to buy cubes and other potential-related items. You start off only being able to buy regular cubes and earn the ability to buy better ones as you progress. They could also make cubes as rewards for some quests and PQs to provide more incentive to do them. These changes would make it fair for all players and provide more incentive to do things other than training and bossing. NX buyers would still have an advantage but not as significant as they do now.

They also need to update every mob to account for potential. Players have gotten stronger while mobs have basically stayed the same.
