I hate how mythic crafting requires specific runes. I have a pile of duplicate mythics and shards I can do nothing with because I don’t have the right runes. All day long the trade chat is filled with what to buy X rune … so annoying. Finally when using the runes they are incredibly unbalanced in power, so you are pretty much locked into a few choices. The whole rune system is stupid and I hope to see it gone in season 7.
I do appreciate blizzard trying new things, and I think it was a good try, but it is pretty flawed, and basically ruins the previous solution of what to do with a pile of mythics you can’t use.
