SPVP Gear?
You need to have chest, legs, and foot armor in order to get armor credit for gear. The armor value used if you have that slot filled is based on level 80 exotics. Outside of that, all stats are decided by your PvP amulet and runes in the “PvP Build” menu accessed at the top of the screen in heart of the mists and during the prep period of a match.
