The only weapons in this entire mod that suffers from accuracy problems during sustained fire are the Bullpup and Bulldog autocannons.
Testing a single bullpup autocannon against 1000 armor vs a Light Assault gun and the same. Both within 100SU
- Bullpup breaks through the armor in 21 seconds
- Light Assault gun breaks through the armor in 20 seconds.
This is because damage per shot has a much higher effect on armor than raw damage per second does, and the Bullpup does more than double the damage per shot. This is while costing 20 less flux per second to fire, and having 15% more range.
The only other weapons that even have accuracy stats in the first place are the Bongo/Bassdrum, which are specifically engineered to cast a wide net to intercept a large number of incomming missiles simultaneously, and the Monogram series, which only has a little bit of deviation.
Every other weapon in the mod has perfect accuracy that never deviates regardless of what ship its mounted on.
As for the larges. The Pellet cannon has roughly equivalent stats to the gauss cannon, except it does 215% more damage up-front, for a 16% reduction in damage per second. It also costs 40 less flux per second to fire. The Gauss cannon remains better against light armor, but the Pellet cannon deals such heavy damage to shields it can often force an overload if the AI hesitates to drop their shields for even a moment. It also used to do the same DPS, but I got complaints that it made the Gauss cannon entirely redundant.
The Heavy Plasma Driver is an armor cracking tachyon lance alternative with *more* damage per second that costs a whole 4 less OP to mount. It doesn't have the tach lance's insane burst potential, but not much in this world should, because the tachyon lance does it so well already.
The Mk2 Bigram railgun has 1500 range, a whopping 300 more than the longest ranged vanilla weapon. If that isn't enough, It is also dirt cheap to mount for a large weapon at a paltry 18 OP, and costs only a little more flux to fire than a hellbore, while doing 260% more damage than one.
Sure, its fragmentation damage so it isn't going to crack armor very well, nor is it going to apply all of that damage to shields. but at those ranges it would be unfathomably overpowered if it could. Use it to suppress your enemies from a position of safety while another ship worries about killing them.
Also the faction has access to basically all vanilla weapons and regularly mounts them.
