No I just think the item you use to make the relics should be tied to the relics, not “pick it up from Rowena”
They could change it so after the first atma grind each new relic cost 500 atma shards of each colour with atma shards being guaranteed drops in batches of 5/10/20 whatever. Just make it somewhat relevant to the quest other than “hey Rowena sells it as usual”
But in the absence of that system I’d rather it use more atma than tomes
