As if armor isn't already suffering from mod congestion already. This orb of power mod is just stupid. We already have barely enough space for the mods we want to run as is. I wish the kill tracker and orbs on multikills we're already a thing on exotics without needed a catalyst for it. As for Master working in general, the material sink isn't even worth the +10 stat bump, which is downright meaningless in most cases anyways. I just do it for the orbs on kills.
