Can we change the grade of Vials from Rare to Arcane or Mystic

[Robens Alexandre]

Since 2017 Arena Master Chest got a shadow nerf without any announcement, making vials almost impossible to get. If the rarity of this crafting item gets increased overnight why not increase its grade also. This way new and returning players will know what to expect and not get scam by other players.

I also noticed that the devs are trying to dodge the subject every time it shows up in forum I want you, fellow players to help me by making other thread related to vial if this one gets closed too, this way they will come clear with us with the drop rate of vials. As people who spend time and money in this game, we need more transparency and an item that is rare grade shouldn't be impossible to get.
