The one shots only happen when you get hit with a high alpha pinpoint like some combination of PPCs and/or ACs. Missiles and lasers just graze the cockpit so it doesn't take much direct damage from them.
It's just an easy way to kill AFK mechs and a frustrating RNG instant kill mechanic when you're the victim. I'm not sure if I ever killed anyone with a headshot, so can't speak much on that end. Sure, it doesn't happen often enough that it's a balance issue, but then what's the point of it?
I don't remember it ever being in any other MW games, but I could be wrong. What do you guys think? Do you think it makes the game more fun with the chance of getting headshots, or just an annoying RNG mechanic?

EDIT: Just wanted to say that after having some constructive discussions in this thread, I have changed my position on headshots as expressed in my OP. I now agree that they are fine and add a bit more depth to the game. I also agree that using the terms "random" and "RNG" to describe headshots is not entirely accurate as it presupposes intent. Also, it was confirmed that headshots were in all the other MW titles.
With that said, I do think a few of the chassis cockpit hitboxes could still be tweaked for better balance.
Thanks everyone!
