I had a teammate shoot at me in the Mantis before, but I have never been killed by a teammate for it. I can see why it upsets people. You don't always get to play with the Mantis and then the one time you get it someone ruins the experience for you just because you got in it before they could take it. It's a massive buzz kill.
