Emeralds reward changes and other ways to earn emeralds.
There are many complaints regarding emeralds earning on leveling up the guardians. I have a few suggestions earning emeralds:
1. Earn emeralds on enlightenment of different ranks. For example, 10 emeralds for green, 25 emeralds for blue etc.
2. Random earning of emeralds for attacking the warlords. For example, 5 emeralds in 10 tries, half price of buying the basic scroll.
3. One of the reward on Battle passes; a lot of people are paying that already and this way can attract for people to pay.
4. Emerald earning on coalition clashes. It should be on CC to begin with.
Otherwise, the developers should just turn it back. No idea why you are making the change because if the people are willing to pay for emeralds, they would do it. If they are not going to pay, none of them will pay anyway.
