I don't disagree here. I'm all in with the replica route they did with the skypirate set. In fact, they should make a system where you can convert the item you get to a level 1 replica by exchanging it under certain conditions (such as having the required job for it leveled up). This way you only create the replica if you're not gonna use that gear anymore.
I'm not sure if OP's intention is to actually have role restriction removed from the gear, where you can wear the level 80 gear on any class. But if it is, then I'm 100% sure that's a hard no from Yoshi P. No point asking about that.
Here I would disagree. People would wear the same gear set for a couple of days and change to something else. Everyone was wearing Krile and Aymeric outfits when they got first released. Now, you don't see them a lot anymore. The same will happen to every new gear. But! your argument would be true in the case we have very few gear in the game. If we assumed we don't have any gear other than YoRHa gear, then if you removed the restriction, you'd see a lot wearing the gear that everyone thinks looks good. With the restriction, you'd force people to look different. But we don't have this case, you have a lot of options to choose from already, and allowing you to use more will increase diversity in this case. Now people are wearing the 2B bottom just for the butt. If more that looks similar got released, you'd see people using them also instead of 2B alone.
Character creation is an example of how you'd still end up with homogenized looks when you restrict the options to a predetermined faces. Only thing differentiating others is just the hair, skin/eye color and face paintings.
Meet Ardbert. I forgot this guy's name in MSQ, but every time I look at him, I just remember Ardbert.
I do agree with this kind of restriction. And yes, I stated before that if they were to implement a system that allows you to glamour other role gear, then they should add a condition that you already have a job that can equip it at the required level. In fact, that would give people more incentive to level other jobs to be able to glamour them. We all know that glamour is the true end game to a lot. It will give even more incentive for others to do old content for that gear.
