I really extremely love, I think it was DivVerent's, idea of giving the laser a very close ranged (no more than 10 meters) 'melee' style attack for its secondary fire, as powerful as a direct hit from a rocket or nex, that might also detonate all incoming fire within its limited attack range and within maybe a 45º arc from where the player is aiming. Refire for this attack would probably be balanced somewhere between 0.5 and 2 seconds. And of course, being a feature of the laser, it would have no ammo limitation.
Essentially, wielding the laser using this attack would add something a little like a jedi academy minigame to Nexuiz, where you have force push, force jump/speed then combined with a kind of lightsaber attack/block. And if you combined it with the jetpack, you'd have a Tribes minigame in Nexuiz.
But it wouldn't make waves in the game's balancing, because it'd take real skill to use effectively and still be countered by fast firing, hitscan or splash damaging weapons, which happen to make up the rest of the game's arsenal.
As was brought up in the past though, the issue is that long time players don't want to give up the 'switch to last weapon' command that is the laser's current secondary "fire". So to get around this issue, you simply make this attack a Mutator (call it Melaser or such), much like the Minstagib Nex, that adds a real secondary attack to the Nex. Problem solved.
If there is any developer or popular interest in this proposal, I could make a new model/texture/animation for the Laser that visually incorporates this would-be new secondary attack, like one with an underslung plasma bayonet or such. I would not be able to implement it on the code side though and would need help getting it from a .blend file (that I'd release of course as part of the GPL) into the a working format Nexuiz can use.
(I can't recall if I was ever able to get a static MD3 mesh exported out of blender, definitely not an animated one though; hopefully a better export script is available since a year or two ago when I last attempted it.)
