Remove high DPS / high energy guns (-> Cerberus Turrets) from NPC caps. Putting such weapons on NPCs, which have unlimited energy, just makes them a little bit overpowered, since 1 Cerberus is about 4.5 normal turret on a cruiser for example - two of these doubles the damage such ship deals.
From all the cruisers and battleships I killed, I can clearly say, that they are bad enough even without Cerberus turrets.
>> Liberty Cap. Ship Captains can't be sold for decent pay on stationary Rheinland Battleships (like Westphalia)
Unlike on other stationary battleships you can't sell them for a decent price on stationary Rheinland battleships. Normally they can be sold there for a price which is a bit lower than on the main sellpoints.
