No the laser cannon is supposed to be an lmg that you don’t need to reload. It only got its buff because people were confused about a weapon with ‘cannon’ in the name, that you have to rest on your shoulder, getting completely blocked by armor. But initially the lascan was completely in line with other laser weapons.
Even the orbital laser weapon only kills chargers and bile titans by reapplying the fire DoT unless you strip top armor first. And the scythe primary weapon is a complete waste of everyone’s time since it is eclipsed by any DMR.
