I don't like the BLM or MNK colors. BLM looks nearly identical but with a slight purple hue, and MNK just looks fugly. DRG is ok but hardly an "upgrade" cosmetic wise.

Honestly PLD is the only one that I feel got a good color swap, and that's cause they just copied the PLD AF / Relic from FFXI (mostly), except they changed the black for blue in the relic (I like the black better btw.). All of the others are just so-so or bad.

PLD Relic in FFXI btw: http://images3.wikia.nocookie.net/__...1/RelicPLD.jpg
