Okay, I'm on a mission fighting the Romulans and some of the time, maybe 30%, they'll fire off their plasma torpedoes at me and sometimes they'll stop and target the ship that fired it or hit another attacker. I don't know how I'm doing it but I like it!
Oh, something else I find kinda cool is when I'm in a PVE battle with the Klingons and they'll fire an isometric charge at me, I won't be affected but it even when it comes back to me.
That's got to be some kind of AI bug, I've noticed the same thing too, Rommies fire plasma torps and the torp wheels around and smacks back into the ship that launched it. I hope that isn't what we're getting when Romulans finally go live.
