Can we please get rid of glamour grades?

[Felis]

They all use the exact same recipe. All the prisms grades have the same price. There is literally no difference between the grades other than making glamour more of a chore to use.

ilevel range.

There is a higher demand for tier I than for tier III.
What it seem you want is put all in a single tier to make it cheaper for ilv1 glamour gears

This, the demand would still be there because "surprise surprise" not everyone has all their crafting classes leveled up or have an interest in crafting.

Because the demand will still be the same, while the supply increase (1 big supply instead of many smaller supplies) the price will drop drastic.
