SE just make a vanity slot to solve all your issues with this.

bit torn on this

On one side I would really like to wear things for how they look rather than stats and better customize my character (instead of having the same WHM robe as everyone else) so something like fashion case would do.

But on the other hand how would all those new pieces be created? Maybe implementing a new job "designer" (or something like that) to create fashion clothe. But then we might end up with many super tacky stuff... I like the SE design. Plus it could be hard to see exactly who is doing what, especially in random group where you don't know people well so you just want to know where is the BLM, the WHM, who is the tank... if everybody has totally un-job-like clothes might get confusing

But it something they should really try in alpha/beta and see how it goes

Huh?

Who is talking about new pieces of anything? The basic mechanics of a vanity tab/remodeling system mean you have item A with stats that you want and item B with the looks that you want. There's nothing new involved. You are using the look of an item you already own to overwrite the looks of another.
