Orbs of Alchemy, at this point, drop very VERY rarely, as everyone surely knows. If this drop rate was increased, players would be able to more quickly upgrade their weapons, and people would be less likely to lose interest in the game, especially when they would have gotten stuck at the various Hall of Heroes missions for several weeks as they farmed crowns to upgrade their equipment. In short, an increase to the drop rate for Orbs of Alchemy, one of the game's most important resources, would greatly increase the playability and popularity of the game, because Alchemy would become far more realistic and attainable.
Personally, I don't see how anyone could disagree with this, but feel free to reply if you do.
I dunno about you, pal, but I have about 12 Eternal Orbs and around 50 Radiants. Go figure. (FYI you can burn thousands of Rads before a 5* item is fully heated.)
I could use more 4* orbs, however. The lower star orbs can be bought somewhat cheaply.
