Personally I've wondered how they're going to implement Lasers in the game. My best guess is that they won't deal instant damage to a target, but instead will do increased damage the longer you hold them on the target. So just spraying over a target won't do much damage, but being accurate and steady with your aim will quickly increase the dps you're doing to the target as long as you are hitting them. Not awesome for killing small fast moving targets, but they'd be great against Heavies or slow moving vehicles.

Just for clarification the scrambler pistol is a laser weapon and has a reloadable powercell.
It may be different for tanks but the lasers will not be weak they will likely be a middle ground between blasters and rails or autocannons and artillery of course there are two types of laser beam and pulse. I am guessing that they will follow a similar ideology as EVE does with enough of difference that it works in an FPS setting.
We will have to wait and see for the most part. Unless ee get lucky and a dev decides to comment on this thread.

I've love to see regular Lasers function as I described above, emitting a beam of death as long as you hold the trigger and the longer you las a target the more damage they take from the beam. Its limiting factor would be the amount of time you're able to keep the beam active. For vehicles this would simply be the Cap meter I described, for Laser Rifles it would be running out of charge in the cell.

I'd very much like to see Pulse Lasers in the game as well. They could function more like traditional weapons, short bursts of damage. This would make sense for the Scrambler Pistol to be a Pulse Laser weapon, and for Pulse Laser rifles and turrets to function similarly.

In EVE the Laser effects closely represent what I described above. The Beam fires, it stays on for a few moments, then powers down and cools off/recharges for the next volley. I would very much like to see this functionality be accurately represented in Dust.
