God breaker is mostly a PvE armor but still very valuable as the bonuses to it are mostly unique. Gas mask, healing, repairing weapons and stamina recovery boost are all handy plus with the AoW update, heavy armor is viable again since the recovery is 0.85 vs 1 that light gives you. Back in the day, I always made it a point to farm warmaker for the gb helm for my thralls heavy armor gasmask with lots of durability. Go ahead and spam shoot those acid arrows.
