No, I'm afraid you missed my point.
There's only 2 refits in the entire Dilgar list that I'd ever WANT. Ever!
Jump Engine? I'd probably be worth 2 XP as a standard refit. I'll do better with reroll dice on crits.
City Levellers? It does the same damage output, but now is more susceptible to interceptors than before. You're paying for a downgrade?! Get Real!
Quick Loading Missiles? Downgrade! Again, you make yourself more susceptible to interceptors, and you also remove your ability to effectively leverage CAF. Never, ever touch it.
Mass Drivers? 2AD of Mass Drivers? Does this set a record for "Most Totally Pointless Weapon System?" I vote yes, I think it's even more useless than a Kotha!
Long Range Targetting Systems? This is one of the two I'd ever want. I'd use it primarily on Heavy Bolter systems to allow them to support the Missile strike, which has probably depleted the interceptors. Heavy ships only where there are enough Bolter dice to matter (Mishakur, Wahant, Tikrit, Mankhat).
Additional Weapons Fitted? You need at least 6 AD, and you can only use this once per weapons system. It's nice for the Omelos and Targrath, principally, but that's about it; it's not like you're adding beam dice. For the Battle-level ships and above, it's a drop in the Bolter bucket, and not worth a reroll die.
Advanced Sensor Arrays? Nah. Your Jashakar is so cheap that if you need additional anti-stealth checks, you've missed the point. Also, the Thorun Torpedobomber with the Aux Craft Pentacon rules is extremely hard to kill without reprisal and is excellent for Stealth-breaking. Garasochs are so cheap that you don't really need it.
Reinforced Hull? Eh. It'd a trade-off, but I'm looking for a benefit. I didn't get it, here.
Supercharged Thrusters? Alright, something that could really help out my Wahant and Roh.... wait. I can't use this on the Assault Ships? Why not? Well, there goes the one good refit. You killed Kenny! You Bastards!
Extra Hangar? Nice. You get 1/4 of a Patrol point. Is that worth even one reroll die? F**k no.
Flight Computer? Not worth it on Dilgar, your thresholds are very low already.
So ... there are only 2 refits that might ever be worth it, and they are on different ships.
My point isn't that the refit lists are unbalanced. It's that they are monumentally unbalanced. They are unbalanced to the extent of some of them being DOWNGRADES that I should be receiving reroll dice for taking. Refit integration makes zero sense until the lists are seriously reviewed for, well, usefulness.
