I'm with this one....trying to do the Legendary Quarry as well as others is too damn hard for one person....why do the Ads maintain their yellow bars or refresh their yellow bars when being shot at?.....i thought ONLY the Guardians could replenish their powers......I'm wasting my time and energy trying to stay with this game....once ya shoot something it' supposed to die period....I'm losing interest in this game as time progresses
