FFXIV comes out - every item that drops off a mob can be used in something.
Great. Wonderful. Fits the whole idea that crafters are actually a class.
However, every item requires around 5 different materials, and each material has 3 different grades of quality. Leaving the realm of great.
Inventory fills up ridiculously fast, and with such a wide variety of items and no auction house, the system is cumbersome and stupid.
Quality of materials +1 and +2 are removed. Regardless, new developers still notice how ridiculous the sheer number of items there are in game and increase backpack size to 200. This is a bandaid to fix a much larger problem.
Now... You would think the new development team would learn from the mistakes which got them into this mess to begin with, right?
Wrong.
Each level of each materia have a multitude of variable qualities, making it so they do not stack.
Welcome back cumbersome design flaws!
We didn't even fully get away from you before we created a whole new problem!
I'll never understand how these people have jobs.
tl;dr In 2.0, when it comes out in four years, we will all have 9000 inventory spaces and 12 retainers because all end game loot will have 25 different variable grades of quality for no reason. Yipee!
