It doesn't matter how much Soul Ash or Soul Cinders they throw at us. What they need to do is get rid of the requirement to have a "corresponding item of equipment of same level" to be able to upgrade your legendary. Why would you need a piece of armor of a certain item level if you are just going to replace that item with your legendary? Seems pointless to farm a piece of equipment you won't use. If you have enough Soul Ash, you should be able to simply upgrade your legendary. This game has become the epitome of "un-fun".
How hard it is to have one single currency through out whole expansion. Would it %^&*ing hurt you idiots in blizz to make single currency to upgrade both pvp and pve gear and earn in both way. How hard is to just reset it when new patch drop so people don't stock up on it. How hard and complicated this is? But now u gonna design 15 different systems and 15 different currency each expansion and each is worthless every single patch.
