Just so you know, AF3 = lvl 70 artifact gear.
Call me simpleminded, but I quite like the artifact gears because of their iconic Final Fantasy look and almost always uses them as my default glamour. This includes tweaking them a little via dyes to make them even more awesome.
However, in order to make ONE set of the AF3 gear dyable, you have to upgrade it FOUR TIMES, and for that you need 3000 protean crystals and 750 anemos crystals. This is not taking the weapons into account, JUST the armor/clothing.
