I've had teammates EMP my Mantis long enough for the enemy team to kill me, and on Exile, I got to the Gauss turret first, so some genius decides to stick the 'hog twice and destroy it. Way to go, guy.
D, I don't even have a loadout with a plasma pistol. If I did, I would actually use it on the other teams vehicles. However, repeatedly hitting me with a warthog because you want me to gun will get you a plasma grenade to the tire, or worse if you shove me out of cover and get me killed.
