Like a lot of people here, sadly i have cosmetics items that are Unavailable to unlock, such as Heartstone cards Back and heroes, Starcraft 2 Emoticons, Overwatch Player Icons etc.
It is sad to see all those items in your collections and know that nothing you can do to unlock them.
My idea is to ask Blizzard to hide all the cosmetic items that are impossible to unlock ( of course it will be better to have the chance to buy them ), at least during the time that are not available to buy or unlock them.
Please give me your support in this request, then you would not feel that you missed something in the game.
Thank you guys for reading, i am not a native speaker, i did the best i could.
