Now that Ep. 20 is out for some time, many pepe's runned the content and farmed for cards and stuff.
The Dim Armor Pieces looks good on paper, but with Nebula and Depth 1 gear on the lose, those Dim Armor pieces cant compete.
With that in mind, not many people try to farm alot of materials. Only run the instances for some Mvp Card checks.

Even with a Marked filled with Yellow shiny Materials, no one buys those. Even worse, after checking the costs for a full enchantet armor set, I was shocked to see that you need:
-over 700 Pure Magic Extract
-over 1000 Crystal of Pure Magic
-And many other Ep 19 Materials (Mostly between 200 and 600)

With that in mind, you only need maybe 900 Runs The Immortal to get a full enchantet set. Reason, Pure Magic Extract are only dropped by 20%.
And as I said, with Depth 1 Armor, Nebula and other Varmundt Gear in the picture, no ones dares to farm and invest Billions of Zeny just to buy an outdated Armor Set.

My Suggestions and ideas:
While the Set is not weak but only oudatet, it need to be easier to get. Armor pieces are super common while Materials arent. So I suggest:

-Make Dim Armor pieces be acceptet by the oven like Dim Weapons.
Those Armor can give guarantee Ep. 20 Materials. Also, those can be added to the Dim Weapon pool as well, but little bit less common. In this case it would be possible to recycle the Armor pieces and farm the materials in every Ep 19/20 Dungeon.

-Increase number and drop rate from Pure Magic Extract and Crystal of Pure Magic
If each run gives like 15 Crystals and 10 Extract, it would be way easier to obtain those. It also gives people an other motivation to run The Immortal and Sticky Sea.

-Reduce Crafting Costs and add them to the Mysterie Box (or increase chance).
Crafting those is super expansive with the value of Flower Petals and other stuff needed. Also Ep 20 gave us a Mysterie Box for 35 Divine Cat Whiskers, where I only got Ep 19 Materials. Removing those and add Ep 20 Mats to this Box should gives those Whiskers an other usage, which can be uset to farm those Mats.

In the end, there are alot of Buttons how to make it easier to grind. People would love to get those Full Enchant Armor Pieces easier for better progression into the late game, or for alt characters.
I would love to hear other idea's how to handle it from you guys as well and maybe hear from the GM Team what they think about it.

Thanks for reading and sorry for bad grammar x3
