Systems:
100 Dust = 1 Unique
1 Dryad/Kalgas Suit = 15 Dust
1 Dryad/Kalgas Part = 10 Dust

Assumptions:
Normal dungeon = ~50min normal (1 player)
Normal dungeon = ~35min normal (2 players)
Hard dungeon = 25min (4 players) -> Can only be done on Ankou, Kheldor with bug
Heroic dungeon = 18min (8 players) -> Can't be done legit, bug or not

Assume guild level 5 buff active, 216min cooldown (3hr 36min)

Scenario:
Let's begin with the scenario of a solo player, running all 3 dungeons to get 3 chips in 3 hours
That's 33 full runs of dungeons to get enough chips for 1 Unique
That's ~82 hours in-dungeon time to get 1 Unique
But if we account for cooldown, and let's say we assume 0 downtime otherwise, running all 3 dungeons 3 times a day would take 10.8 hours

**If that's the case, it would take 11 days of farming for 10.8 hours a day to get 1 Unique**

Now if we consider that dungeons will get fixed/more difficult, more players will be needed to complete dungeons, and therefore drops will be split

**If we consider the scenario of 2 people on normal, that's 22 days of 10.8 hours a day for 1 Unique each**

The split time gets even more ridiculous if you do a linear 1-2-3 chip droprate across the difficulties, as the increase in players required is exponential (even though it's not even possible right now)


All of these calculations are assuming a perfect scenario, assuming nothing gets more difficult or fixed; it would only be worse otherwise
