It has a lot of dakka.
Not really. No auto-fire, AP damage only mildly higher than most shotgun slugs and totally outcompeted by sniper rifles, HE and incendiary worse than handheld or GL versions.
If sniper rifles didn't exist, you might have a point. But they do.
It does have a fast snap shot and pretty high-damage shot shells, but low accuracy means they're really not that much better than other shotguns at range.
For the record, I don't think the LC is
bad. I see it as a perfectly reasonable weapon whose strength is the ammo variety and weakness that it's a mish-mash of different functions that don't work that well individually. Kind of like a 'realistic' handheld cannon would be in my imagination, a niche weapon used only by guys on super-soldier serum because everyone else knows it doesn't work without mounting it on a vehicle.
The big cannons are when you get the actual dakka. The LC is a weapon with a (non-optimal) niche, and pretty useless to people who want every soldier to be optimised for what they do (like Vakrug

). Nothing OP at all.
I'm not paid to write 2 hour speeches. Take it or leave it.
But you can and do come up with working 1-2 sentence reasons all the time. Just not all the time, and not when you get defensive.
