I've been looking at the amount I've accumulated and noticed that i never use any of my 62 primal sparks and wish they could be more useful while i look at my 15 forge sparks and notice i don't collect them as much. I'm thinking there should be a section where it takes a few materials from each token/spark section (excluding boss items) OR takes the materials that aren't in any of the sections and put them in a general section where you can use any of your sparks or tokens.
Negatives I'm expecting to hear:
Will really benefit new player more than experienced ones.
Will only be helpful with rare items
I know there's going to be more, powerful, arguments against the idea but i thought i would throw this out there.
Most people trade them in for the high level trinkets. But yeah, theres a hugely disproportionate rate of getting Primal sparks due to treasure vaults being considered beast levels, and how common JK runs are. I also rarely see grim sparks in levels that give them, and never in grave yards unless it has a treasure gate.
