So we know that a Guardian has their special abilities using light such as creating grenades, teleporting and supers but what about their physical abilities? How fast can they move on foot, how much stronger are they compared to a normal human being? What about endurance, do they ever tire or will they continue as long as they have light in their systems? If anyone has any feats via lore (gameplay works too but I think it will be taken with a grain of salt until Bungie makes a destiny novel like we keep on asking for) write it down and if you know it the character and his/her class.
