I've gotten all the other triumphs for the gambit seal except for the light vs light medal meaning i've reset my rank 3 times killed the ascendant primeval enough to get the ship and sparrow, i've earned malfeasance and I've had a team-mate bank 100 motes in a single game but for the life of me I can NOT get kills of invaders while they are in their super. When someone is invading they will almost always use a heavy instead of a super I never got the opportunity to get the easy invaders in their super kills because I lost my internet for 3 weeks the reset after last wish dropped. I've only gotten 4 invader kills while they have been in supers and im about to get my fourth reset. I've had enemies explicitly avoid me when they are in their super because of team wipes while i'm invading. The chance of me getting a opportunity for killing a invader in their super feels more rare then the chances of getting the ship and sparrow for gambit.
