Why make it so difficult to gear up our non-caster DPS?

[Felis]

I don't see the reason that a ninja should look exactly the same as a bard just color inverted or a monk should look like a dragoon color inverted, that is just lazy gear design and if they are going to be lazy go all the way and just share the gear. To me it looks more like they were making the melee gear first got lazy half way through and just color swapped a couple then got to making the tank and caster gear and said screw it, just let them share even color swapping is too much work.

MNK and DRG gear have different Def and Mdef stats. Also only the tome gear of them share the same model (if we are talking about the new 2.4 gears)
