I've been fighting a lot of Luddic Path so I am familiar with the Mk II. While it does make for a fun beefy opponent its basically a oversized frigate with a hammer launcher strapped to the front.
I owned one at some point and it basically doesn't have enough OP for any decent weapons, let alone mods.
It's not a viable warship by any degree, it's mostly a damage sponge for the LP's frigate swarm and a carrier for most of their hammer torpedoes.
It'll mess your face up if it had support and is allowed to fire hammer wave after wave, otherwise you just fill em with lead and move on to the more dangerous LP carriers and annoying speedy frigate swarms.
