This assignment is taking way too long to get done. Adrenaline effect lasts way longer than the kill window for the assignment. I have no idea if this is by design or just a glitch but its crazy that you have like 1 second to get a kill otherwise it just doesn't count. The window should be as long as you have the adrenaline effect so that this challenge is actually semi doable.
I have died more times trying to get stuff to work - ie adrenaline boost - timer does not come on - no kills recorded been stuck at 7 kills for over 2 weeks - also mouse 3 and 4 just default mid game - sniper shots not registering - and during a takedown I kill someone then get shot but no credit for kill and as to go through whole take down video to register a kill and just a sitting duck meanwhile - wasted more time trying to get the 30 adrenaline kills so I can get the spawn in gadget to do this weeks challenge so gave up and left the game
