I've been noticing one particular player in a bug-ship who's been surviving getting reduced to 0% hull a *lot*. I've seen him at 1% with no shields, taking hits from multiple players, and then he vanishes. It's not just sensor jamming, because if it were the torpedoes tracking him would still hit, and the torpedoes do hit and explode.
I *think* that he's logging out quickly, and then logging back in a few seconds later, but I'm not positive if that's even possible.
Either that or he's just extremely lucky. Or he's running some sort of gear that I'm not aware of (I've been away from the game for most of last year). I wouldn't put it past Cryptic to add some sort of I-win button. I'm just not able to tell what's happening. He seems to be getting hit and taking damage, but instead of dying from it he disappears for 20 or 30 seconds, then comes back.
