I disagree. You use more poison scrolls. They drop for me just as much as every other scroll. I have less fires scrolls, because I use them. I have yet to see any disparity in scroll distribution with regard to the element. Even your level 12 VIP Swivel, you won’t see an uneven distribution of scrolls due to the games coding. It isn’t built for uneven distribution of resources based on element. This is clear at all stages of the game. Some adventures give specific scrolls, and if you play a lot then you will acquire more of that scroll. Nobody that I can tell has adjusted the distribution of poison scrolls any differently than any other element. Point in case, I have more Dark and posion scrolls than I do any other element. That would not be possible if your assertion was founded in fact. I hope this helps you feel better in understanding that nobody is limiting poison scroll distribution in the game.
