Yeah...Kinda wish it was possible to dye multiple parts of our equipment.
The way they have it now is just so arbitrarily chosen it doesn't really make sense for most items.
As is evident in what you posted.
Two basically similar item styles, but dyes work differently on them.
Just doesn't make sense.
You should be able to dye separate sections of armor, including the belts and chains or what have you that are on them.
I guess PS3 limitations, as Evangela said is the culprit.
But they could still include it and just not render it on PS3 systems.
So people that can see can still see it but those with slower processors or whatever only see theirs and basic shades on others.
(I might be ranting incoherently because it's late and I'm sleepy T_T )
