I would think some specific builds could enjoy some Dex Cloth or Int Plate or whatever. "White" quality armor I'm fine with as is, but I'd like to see more variance in MA/PA on the gear and or restrictions if it's very good (right now 11 is about the max needed for anything). Right now if I see a lot of phys dmg enemies I just swap out to more plate, more magic casters I put on more cloth. I expect to see some high MA plate or high PA cloth in the final build, it makes it more flexible to me. Min/Maxing or RPing you may still want that pure leather rogue. There's tank and magic rogues out there though that need other stats more than finesse.
