Old 1.0 Weathered Equipment - Vanity Cross-Class

[Enkidoh]

Sadly it won't happen - dated gear is old version 1.0 gear that existed prior to a specific patch in 1.0 added new equipment models, and the old stuff was retroactively renamed 'dated' equipment. I still have my old dated 1.0 equipment, and indeed you can use it irrespective of class (this is actually reflective of the fact in 1.0 originally there were no equipment restrictions - you could give heavy armour to mages for instance, although you were penalized stat wise severely).

But the ability to gain them is removed from the game - it was one of the first changes SE mentioned was going to happen with ARR's development, as mentioned here:

Items to Become Unobtainable
The following items will become unobtainable:

Dated items
Weathered gear
* Weathered weapons and tools will remain obtainable.

Items to Become Untradable
The following items will become untradable:

Dated items
Weathered gear

So yeah, only those who transferred a character from 1.0 will have dated/weathered equipment - it's not attainable, nor will it be available again either, as it's basically obsolete. It's why I haven't converted any of my dated gear to materia - I like to wear it for vanity (and sentimental reasons as well).
