[Opinion] Myth Expenditures are Absurd

[Samburi]

Star-3 Mat's... cost Myth, sure we can buy them at the MB but they're costing some ignorant person their Myth or hindering progress for another. It's fine that they do, I just feel there already needed to be another method of obtaining them (I feel like I'm cheating people from their Relic quest-line when I ask to buy the materials off them for gil, just my own personal issue... but still, it feels crappy).

You should know this since 2.2
Coming 2.4, a new tomes come ingame and myth vanish. Crafting mats you can buy now with myths, you can then buy with GC seals or farm them in the 2.4 dungeons.

The one thing that I'd like to see is not in your list.

Make it possible to purchase materia with GC seals.
Require GC rank x for materia rank y, and scale cost accordingly.

And crashing the market? good idea
If you want materia outside of the MB, do lv40 leves to get the gears you spiritbound then. And level up your Chocobo while you do it. He is usefull for the Novus part.
