Hi there, I think there are a couple things can be easily improved:
- Giving more things back after duplicating max-sig 6 star, e.g. more ISO-8, some class sig-stones, more gold
- Allow player with 6R3 to buy level-4 AW/AW potions from glory store, this should have been changed long time ago.
These small improvements only require tiny bit of efforts and they could make players feel so much better.
