This may be common knowledge and I'm preaching to the choir, but I've seen a lot of people doing this, so I figured I might as well make a post. The weak point on the Vex is not on the head. So you should never headshot them, since all that does is knock their helmet thingies off and cause them to charge, which can be overwhelming - especially in the higher difficulties. So if you're looking for precision kills, whether it's for a bounty or just in the name of efficiency; shoot them in the gaping white hole in their abdomen. An added plus is that sometimes you accidentally shoot them in the crotch which makes them flinch, and because I'm a manchild, it's hilarious. I can't seem to find this weak white spot on the Minotaurs or the Harpys, but the bottom line is: [b]Don't headshot the Vex, ever.[/b]
