Just checking briefly on Mark IV vs Core Guard Posts and I noticed a few things. First, Core Worlds (the Mark IV systems adjacent to AI homeworlds) actually have Mark V guard posts, with Mark V stats, while the homeworlds have Core Guard Posts with basically Mark VI stats (20% more health and DPS than Mark V). However they often have a few odd stat tweaks, such as ROF or damage that might be making them less effective overall. For example, Core Missile Mark I-V have 30k range, but Core Missile only has a 12k range! It also has a different set of hull multipliers and gets only x4 instead of x6 against those hulls. Against Ultra-Light, a Mark V Missile GP does 12k DPS while a Core Missile GP does 16k. Notably, Core Missile GPs do NOT get a hull multiplier against Polycrystal, while regular Missile GPs' do (and get x6 at that). Therefore, against Bombers, non-Core GPs' deal x3 DPS and from a much greater range.
