At 23:04 you can see a bug with contested health. You had contested health available when you started the execution, but rather than the execution restoring it, you lost it *during* the execution. Great.... so now it looks like, in their attempt to cure the contested health bug that went in favor of the player, they made a new one that goes against the player. Ah well, at least it doesn't happen all the time.
If you go frame by frame you'll see he lost the health after pressing the button. it seems there's a brief moment after triggering the execution and before the actual animation starts (basically when your character walks towards the target) where you are vulnerable to ranged damage. if he had pressed the button right after taking the dmg it would've locked the constested health I think. it's probably unintended yea but it's pretty inconsequential
Enjoyed the video! I main as the Sniper class. Finished this mission on lethal with the bolt sniper. Not sure if you already answered it but between the bolt sniper and the stalker which do you prefer for damage output when playing with randoms & solos?
