I'm currently suprised how stone prices recently dropped, like always i would sell u46 purple for 1kk, now it's worth like 400k and you can buy it for 300k if you are lucky or even cheaper.
The rarity of the stone drop is rare, and i don't think prices should drop.Same goes with blue stones, i can say dbog is dying slowly and changes must be done with the game and i mean alot of changes.
