@Paris (I did skim, but I had read it normally a few hours before I posted.)
Also consider that with 4 tokens, you can give a laser rifle a generator, allowing for almost unlimited ammo (unless you melt it by firing continuously) while the Shard Rifle, even with the 4 token upgrade, still runs out of ammo after 40 turns of firing.
So you get comparable magazines to the laser rifle, even though the weapon is slightly more powerful))
You didn't mention the cutting laser, but you did mention the PSL- the four token upgrade to the Testament's magazine is the PSL tank. You could, with a bit of Handiwork, do a similar thing with the Cutlas battery, and I doubt it'd cost more than one token to mess with the electronics. So the lasrifle has a better ammo economy when scaling up. It also has a even better ammo economy when just using a generator, because that costs two tokens, maybe three or four if you're getting a custom job. So, if we made lasrifles with generators standard, they'd be equal in price to a Testament, but have infinite ammo.
Mostly, I'm disagreeing with your comment that the magazines are comparable. A lasrifle's ammo economy is entirely superior if you're going to spend tokens on it.
I should really check if a lasrifle can be run at any higher power for short periods without taking permanent damage, and then just make a variant with a weak generator and capacitors, like Nik's old pulse rifles.
As far as the vibrope... fine, vibroblade, even if it's bad at cutting... I didn't say to start production, did I? It's got similar performance to a monorazor in combat, but trades mundane utility (cutting well) for the ability to kill synthflesh and Battlesuits. But it's waaay too expensive to replace a monorazor, so before I even check if there's other things that might disqualify it, I'm gonna check if it's even feasible to produce
