What's are the plans for Dogi Balls in the future?
They force players to wear dogi's, masks, hats, etc, in order to have stronger character, despite dogi's and such being originally meant just for aesthetics. Dogi balls were also very P2W encouraging. That said, they were a fun way to add some extra customization to your character. Maybe add that extra 10% attack speed or energy for example.
So what should happen to them? If they can be made non-cash shop exclusive(Craftable? CC dungeon? Time Quest rewards?), and be applied to your gear instead of your dogi, that'd be pretty sweet in my opinion.
