The "paintball speed spit bolt" looked awesome when the ship came out of warp though, even if it was more Wars than Trek.
Didn't the Kelvin fire beams at the Narada? They weren't speed of light, but close enough
I do remember the Kelvin firing beams. They were a bit like TNG beams.
Personally I think an instantaneous beam of energy that last for as long as you squeeze the trigger would look fuckin' cool as shit.
They just haven't ever tried one on Trek. Enterprise came close though.
