Melding: The entire system is a multiple different systems mixed together into accomplishing the same thing. Each have different costs and methods of doing things, and they're all confusing and needlessly complicated. To fix it I would have liked to see a single system where you exchange various items for currency, there could be multiple different currencies if you want to lock certain things to certain points in the game (LR, HR, MR, end game etc). And have you just throw in a ton of stuff to get an amount of currency back. Then just use that currency to buy the things you want like a shop. Instead of this constant back and forth with different trade offs and 3 of this item for 1 of that, or 2 if of this quality, etc. That would make people want to interact with the system, and not just feel like it's a titanic chore they have to go through a couple of times, and then go back to ignoring it for being a horrible experience.
