Crystal vault organization
There is so many different kinds of crystals we really need better organization of the crystal vault. A simple change could be to sub-divide the Crystals and Shard Crystals tabs to hero and related rank up crystals, relic and related rank up crystals and miscellaneous, or whichever way makes sense.
Would greatly help with the user experience, as right now it takes a hot minute just to find the crystal I want.
