Why do people think the lucifer's flux cannons should be ... well, BEAMS?
It felt much more EPIC watching them travel through space... it was swift, but there was still some time, it made you feel like NO!!!!!!!! but then it's too late, instead of just frying it from range. I think you should make a high quality FS1-style flux cannon effect, rather than assuming that they made it like they did in FS1 because they couldn't make it any 'better'.
Making it a beam is like playing the bullet-time scenes in The Matrix at 10x full speed.
Don't make it a beam. The FS1 way prolongs the feeling of doom, as it was meant to and ought rightly be.
