Suggestion for people to receive the Iri Fragments back if they buy the DLC
Let's say someone bought a character with iridescent fragments (9000 when not on sale) and they bought the DLC with real money later, I think they should receive the fragments back, or maybe just half of the amount they paid. This would incentivize people to spend money on DLC instead of spending an in-game currency that pretty much doesn't do anything to the developers.
I unlocked Mikaela, Jonah, and Artist with fragments without realizing that by buying the DLC on Steam I would have received an extra cosmetic for each character. But now it's pointless to buy the DLC (even if it's on sale) just for a single piece of cosmetic, but if I have to receive my fragments back I would have done it with no problems.
I personally much rather spend iri fragments only on cosmetics now and real money with characters, whether they are original or licensed.
