Before further nerfing destroyer/cruiser damage, I would suggest boosting frigate HP.
Homeworld 2 horribly skewed balance in favor of destroyers and battlecruisers. The armor ratio between these units was vastly changed. Frigates had a much greater proportion of relative health in HW1 compared to their counterparts in HW2.
Look at these ratios:
HW1:
Frigate Health
12,000-16,000 (not counting field frigate)
Destroyer Health
44,000 (Frigates have between 27.27% and 36.36% relative health of Destroyer)
Heavy Cruiser Health
90,000 (Frigates have between 13.33% and 17.77% relative health of Heavy Cruiser)
HW2:
Frigate Health
12,000-16,000 (not counting marine/infiltrator types)
Destroyer Health
85,000 (Frigates have between 14.11% and 18.82% relative health of Destroyer)
Battlecruiser Health
240,000 (Frigates have between 5% and 6.67% relative health of Heavy Cruiser)
What the heck is with this kind of disparity? Itās almost like Relic wanted frigates to be useless. Add in the RU cost to armor ratio and the comparison becomes even more ridiculous.
Whatās the solution? Bring frigate armor value ratios closer to where they used to be. Using the ratios above and rounding for ācleanlinessā you come up with this:
Frigates with 12,000 armor => boost up to 32,000 armor
Frigates with 16,000 armor => boost up to 43,000 armor
Destroyers/carriers are also weaker with armor ratio than they used to be. In that case:
Destroyers at 85,000 armor => boost up to 117,000 armor or thereabouts
Carriers at 80,000 armor => boost up to 192,000 armor or thereabouts (Vagyr carrier to 132,000)
Note these ratios are determined by using the 240,000 HP value of battlecruisers, not the 200,000 of heavy cruisers. Will this fix everything? Not really, but it is one piece of the puzzle.
