TBRs (Tractor Beam Repulsors) various pulses, various distances various re-targeting and takes longer for torpedoes to reach ships in some cases. I've observed and noticed with the same person clicking it all the time can make the game last longer.... yep fun fun. Only useful use they have is when you're tractored and things might explode on top of you if you don't thus saving 30-60 seconds at best of having to respawn.
its actually one of the most useful things when you are in a pug for some elite stf. with that power, you can push back the spheres in infected, the assimilated klingon ships from the kang and in KA, you can push back the probes. saved a lot of stfs for me
