So, finally built the Battacor, and, well, I have mixed feelings about it. Aside from the effort required to really improve its damage output, the only instances where I'd see the need to use a normal rifle shot over the Opticor would be against Juggernauts (the Opticor struggles to do any damage to those things for some weird reason), and even then I'd just bring a Soma with corrosion. It doesn't help that the Battacor uses projectiles rather than hitscan for the regular burst, meaning hitting anything worth a damn at a distance is significantly harder (seriously, I am struggling to hit moving targets beyond mid-range), and the charge shot feels kinda iffy compared to the Opticor's. I really feel like I'm not dealing damage reliably at all with this thing.
Really, I think it'd work significantly better if it was a Mega Buster-style weapon - primary projectile fire good for mowing down individual weaker enemies, but with a large secondary charge shot projectile (with a high enough charge time that using it outside of its intended use case(s) over the primary fire isn't practical) that rips through entire groups like a hot knife through butter or does a lot of damage to a much tougher enemy. Granted, a Mega Buster-style weapon has been something I'd dig the absolute hell out in general.
