Ship gun damage is now mitigated by the ground character's armor, including increased armor protection from buffs/specials/abilities/expertise. Ship gun damage is Energy based. The combat spam (in verbose mode) when the ground character is hit by ship gun contains the mitigation information.
Each missile launcher is now on its own independent cooldown. A ground character with multiple launchers can fire another launcher while the other one is on cooldown. At most 2 launchers can be on cooldown at the same time. Once 2 launchers are on cooldown, you must wait until one of the launcher finishes its cooldown before you can fire another missile. The shared 2–3 seconds warm up time remains.
