I support the intent of having the regular essence being abysmally high (pun intended) to get new/returning players catch up to the active players right now.
But... an issue that I'm starting to see right now is the oversupply of Deep Abyss essence because they are essentially unusable until a players gets x139 regular Abyss essence. To counter this, maybe we can get DA essence be arcane-able into Abyssal essence as well for like 5:2 rates?? I'll leave the rate calculations to you.
As for Partial Enchants, I agree with Perro's.
