Laser Cannon vs Illuminates

So I've been running with the laser cannon for awhile now against the illuminate. It takes down the medium armored enemies rather quickly esp. when beamed in the head.

It also seems to handle the Harvesters in less than 1 heat sync when beaming the weak spot on its leg joint. It also signals to my teammates where I am targeting the Harvester so they can target the same leg joint with their weapon of choice for an even quicker takedown.

It can also clear voteless hoards although I usually pair it with a spray 'n pray for more efficient hoarde clears. I also don't feel as much pressure to be perfectly accurate since it recharges it's ammo quickly enough, esp. in cold climates

Despite all these facts I laid out, I hardly ever see anyone using it. Am I giving it more credit than it deserves? Are there better options? Do I need to just get better at handling recoil and landing accurate shots with machine guns, AMR, etc.?
