Why Eldritch Ember currency is more expensive than Ichor?

Just curious as to why. Is there a specific implicit that is more desirable from Ember? Or Ichor is just easier to farm?

my belief is that more people went to the right side of the atlas passive tree.

which would lead to more people taking Eater passives, and then running Eater influenced maps, and getting more Eater currency.

and i mean, really, right side best side. Harbies, Expedition, breach legion abyss delve... no contest.

Eater of Worlds (and its influence) is generally more popular to farm. You can see the same effect with Forbidden Flame and Forbidden Flesh jewels. I literally paid over 15 times the price for my Forbidden Flame compared to the Forbidden Flesh one even though my understanding is that they should have roughly the same drop chance if not exactly the same.

I don't know other people, but I just refunded every point that had to do with Infinite Hunger and Eater of Worlds, I would have stopped playing the game if everyone else didn't say how bad Infinite Hunger is.

So almost same drop rates, but The Black Star is playable at the very least, so no wonder people actually play that boss and farm ember currency
