Torps will follow you over the 10km mark.
I believe the hit/miss is calculated at the point of firing, so moving out of range doesn't save you. I'm assuming this is done so that the annimation can be done correctly.
I believe the torp hits will track you even if you Subspace Jump behind your attacker.
A more recent one. The Borg Spheres seem to hit you with something that makes EVERYTHING go on a 2-minute cooldown. This goes for BOFF abilities, weapons, and even using full impulse. And if you die, which you very likely will, and respawn, the timer is still in effect so you can't go to full impulse to get back in the action, just snail your way there hopefully in time to not totally botch the whole mission.
Today was totally the first time I had ever seen something like this in any Stf, so I don't know if it's unique to this one for some reason or just a side-effect of the last 'patch'. But I bet there are lots of people seeing blood over it.
