Assassination challenge is anti-teamwork

Too many times today have i been in a 2v1 situation only to find my ‘teammate’ not shooting, but instead going for the assassination. Not only does this put myself at the risk of dying in a position we should easily win, but i’m obviously going to steal the assassination if you get it.
I love the whole challenge aspect of the game, but please can we make them more win and weapon kill related rather than absurd challenges that takes focus away from the main objective.

Just play as as comes natural, you should be able to achieve this goal within normal gameplay. The situation you described is a bad example of lack of teamwork. In fact, it is a good example of teamwork. One player acts as a distraction while the other assassinates. Maybe you should’ve thought this through first

I recently had this happen to me in a game, I had low shields after putting down a Spartan and another came in front of me shooting, I would’ve taken some cover but instead I kept my offensive since one of our team came into help but instead tried to get an assassination trying to get behind him instead of shooting, I died, he shot the guy when I died so he didn’t.
