Re: Duplicate Heirloom set bug
They did state that the bloodhound heirloom would be added to the standard loot packs so technically they are well within their rights to refuse this.
However, should heirloom items even appear as duplicates? It's a serious two's up to anybody willing to invest that amount of money into the game frankly. @DragonRisky If i was in the same position as you i doubt i'd go for another heirloom item in the future knowing i could potentially just end up with another duplicate.
I hope the community managers read this and pass it on as feedback.
