Please consider adding the magic wand system from KMS to GMS for interactive worlds. Currently it is way too hard for newer players to potential their gear without it.
If the magic wand system is not being added, it would be a very nice quality of life to have the solid/hard cubes from bosses be tradeable, people already do services for it so it will make it safer and more convenient.
Allowing Interactive worlds to roll their potential and bonus pot with mesos would be an amazing improvement and health for the game. It will also be inline with korean version.
