It's Been 20 Years

And we still don’t have a cosmetic blind fold and eye patch for plate bois… How is WoW so innovative yet so outdated at the same time?

Yup.
This is the closest you can get.

I don’t have a blindfold for plate, but I do have a cosmetic eye patch, various hats, multiple bandanas, hoods, and glasses.

Realistically I think it’s time to just make most gear pieces available to any class / armor type. I get that they want classes to look like, ya’know, their armor class, but with so many cosmetic options now I feel like it just doesn’t matter anymore and we should let people make the outfits they want, barring things like class-specific sets / pieces.

It’s weird to me too, because a lot of the restrictions just feel like they don’t make sense. There’s a yellow vest called Recruit’s Vest which is a plate armor piece. There’s a palette swap of the model called Brocade Vest for cloth wearers that is the same model, but black instead. I feel like a lot of leather and mail pieces look similar too; like if I passed a rogue wearing mail, I probably wouldn’t notice. I’d give up the little bit of immersion to have my entire wardrobe available.
