I play with a Sunsinger warlock who uses fusion grenades and today in the crucible I stuck a nightstalker hunter with a fusion grenade and he only lost 2/3 thirds of this health instead of all of it. Does the nightstalker class have some ability that can grant them an overshield or a new exotic that gives them more armor? I thought it might just be a connection problem but it happened in several matches so I am I just unlucky or is there a reason?
