Hi I would suggest the possibility to "disassemble" dogis. Currently they lost a lot of value, since there are so many in circulation, being able to disassemble to obtain items would give more value.
For example disassembling a dogi you get a dogi ball excellent (80% chance), rare (15% chance) or legendary (5% chance).
The dogi ball is just an idea same for the % rates, the important thing is to be able to dismantle them and get something of value.
