It'd be nice to be able to use a limited selection of the robe models for custom armors. Outside of the general cloaks and whatnot, there are some nice models in there, particularly the tabard loincloths.
Every set of armor deserves a duster.
Just saying.
because it's:
A: More intensive to add than realized, relative to other things our technically minded team members would like to be working on
and
B: Wanting to keep these options in DM hand for more flavorful options when rewarding players…
This will not likely happen.
