I realized that there may be a problem when I rushed a sunbreaker from behind and pumped three invective shots point blank into his back and he turned around and one shotted me. Then ran off to kill the rest of my team. One more shot would have killed him, but man is that ridiculous. I can easily shotgun a Warlock from behind while fully charged in sith mode. The titan super, as it is now, is as close to temporary god mode as you can get in destiny PvP. Hunter tethers can shut them down, yes, but why should one man's super be required to simply shut down another's? Also, as I have learned many times so far, the delay a tether has before it kicks in is more than enough time a titan needs to lob a hammer. I'm usually dead before I hit the ground after the bow animation.
