This problem happens when we can only loot Lv30+ chests. We will get mountains of mythic materials, some legendaries materials, and, sometimes epic or lower level laterials. This is weird, we need a balanced drop rate, not give us tons of mythic, which is useless in most situation.
This problem is still unsolved after recent QoL hotfix. More epic, less mythic please.
OR: add a new function, let us use superior materials to replace the inferior one.
example: if I tried to evolve an armor without enough proper rune, pop such window: “you have no enough epic runes. Use 3 mythic or legendary runes to proceed?” and let us choose which one to spend.
