Sidearms as specials would make them even more unused (if that’s even possible) so keeping them as primaries is a necessity at this point. Linear fusion rifles seem to be good in the heavy slot, though. Seems like precision, long ranged weapons are scout rifles for primaries, snipers for specials, and linear fusions for heavies. Perhaps buff their damage if needed but I believe they’re best in the heavy slot since nothing else seems to fit “long range” engagements for heavy weapons while also having a decent ammo pool. Swords are particularly useless as heavy weapons primarily due to most bosses being impossible or difficult to attack consistently with a sword, leaving them to be more add clear weapons where the risk of dying is minimal. A heavy weapon that can’t damage the boss effectively is a very useless heavy so either change the boss encounters or make swords a special weapon (the latter of which is much easier to do).
