you should add abit where we can buy shards with spirit stones say 1 star person 1 shard = 25 spirit stones up to 4 star person 1 shard = 100 spirit stones
I would have to agree with Keith.
Two weeks ago I had 0 spirit stones. I use spirit stones to upgrade my gems every chance that I get. And yet today, I still have an additional 350 spirit stones that I can't do anything with. So coming up with an additional reason to use them makes a lot of sense.
The larger issue, in my opinion, is that the crafting needs some updates. Crafting is a cool feature, but there are still multiple items being dropped by the buildings that are not being used anywhere in the crafting recipes, and still some balance issues such as Keith points out.
Emily, I am getting Spiritstones almost every battle. Shard, not so much.
I agree that the crafting needs updates. Like using the alter stones for crafting materials for star gems.
