OHD is looking to be a semi-realistic shooter, killcams are not exactly the best option for that... If you suddenly died then you simply did things wrong, not taking cover, not advancing correctly, checking your corners, flanking, using smokes, listening to gunshots, etc
Imagine being a sniper knowing the first kill you get is going to reveal your position, weapon and range for no reason lol
That's more appropiate for casual mods, not the base game unfortunately
