As a quest reward, my Jedi Guardian was offered the choice of two orange robes, one heavy armor, the other medium. They appeared cosmetically identical in the gear preview window. Since the stat values of orange gear is governed by the doodads slotted in them, it made me wonder why the choice of two more or less identical items would be offered.
Is there an armoring scalar or something that goes higher with heavy armor? If not, does that mean my Jedi Sage could eventually get stats identical to custom heavy armor despite being limited to light armor?
