Masterworking Materials Rework Suggestion

Why not gives us only ‍Neathiron ?
I don't see the point in going through Alchemist to transmute an ingredient to obtain Obducite and ‍Ingolith.

For the Rank 1 to 4 : Need 1 , 2 , 3 , 4 ‍Neathirons

For the Rank 5 to 8 : Need 8, 16 , 24 , 32 ‍Neathirons

For the Rank 9 to 12 : Need 50 , 100 , 150 , 250 Neathirons [Unchanged]

Simpler, right ?

[Edit 1]
But having around with lots of different ingredients is not necessarily a good solution.

And as proof: The devs have reworked the “herbs” in game. Instead of having +9 differents herbs in our resource tab, Now we just have "Bundled Herb".

In addition, with the future Season 5, the devs says (in Patch note PTR): "Gurgling Heads" have been removed from the game. (Mats Boss for Varshan)

So here, proposing to group the materials of Pit into one is not such a crazy approach.

[Edit 2]

Finally, this is what is currently happening on the PTR 2.0 Neathiron and Ingolith have both disappeared to become only Obducite ;) I was right... :p
