Why the emphasis on PvP? As stated in game its only a training exercise, you do know there are legions of darkness out there that need to be dealt with? Training will not win the war, guardians need to patrol. You think eva levante can gather all that temper cloth to make new shaders on her own? And just what will happen to the munitions supply when banshee doesn't get his shock cores? PvE guardians do all the real work keeping the tower running so you can mess around in the crucible gambling ring.
