Angel Essence is unnecessarily expensive

The first levels of Angel Essences are expensive, I haven't been able to get them to level 8 for years.

I think this is everyone's problem. It should be cheaper and more accessible. 2 3 4 5 6 7 8 9 10 very expensive. Angel Essence combos are equally expensive.
