OPTIMIZE EQUIPMENT button, why not?

[Felis]

Considering the incredible time-sink that simply going through all gear in my inventory ─for all slots─ is everytime I want to switch job (or, more often, level up), I would very much welcome an "optimize" button.

That get fixed with 2.1
But it is called "sort" button, not "optimize" button.
You would can sort for ilevel so you find that equip with the highest ilevel.
I hope that we can also sort for other stats, so I can as example find the equip with the highest crit rate.

Please explain that.

Why would something "remove choices", when it's just a button that you can CHOOSE not to?
if anything, it'll ADD choices.

It would choose for you

Or just give every class their own armoury tab so it dose not get confussing....

This would confuse lot more
"Where is the robe for my ACN? Oh, in the CNJ tab."
