Its time to remove job-based glamour restrictions.

It's not how I think though, it's just a fact. You can choose to accept it or not. DPS is the ONLY role with the jobs therein are further broken down. Pull up your character screen and it's right in your face. If you're implying that DPS gear is actually more job restrictive because of this categorization of the jobs, then I get it. But all of them except NIN share gear with a least one other job. To a certain extent, DRG as well, but a lot of their gear can also be used/glamoured by tanks.

Im not quite following what you're saying btw.

There's gear thats tanks and DRGs
There's gear thats healer and casters.

So I can only assume u mean gear within a group, such as within tanks? but then id say there's gear thats DRK only, WAR only, and PLD only.
The rings in Brayflox are examples of this as well. (excluding AFs, and the most obvious, weapons)

Unrelated.
I should also mention all Dated gear from 1.0, wasnt class/job locked then, and after the update remained unlocked, and could be glamoured by anyone who still owns the gear. I have chainmail that can be glamoured to any class, and leather armor.
(Sadly didnt get enough gil to buy the platemail in time, before the update, was 500k short)
Wish I could make/buy that stuff again, just for glamour as well.
