Alright, goofing around with that a bit more is it possible to see the AI's multipliers for different ships somewhere?
It's not visible in-game but can be computed from the wave-calc-log line "after applying UsefulnessInAIWaveMultiplier if any, numberUnits : "
But for reference the wave-eligible types with non-one values for UsefulnessInAIWaveMultiplier:
Fighter: 1.2 (bonus types are typically at least 20% stronger than triangle ships, so this prevents "pick fighter" from being a nerf)
Frigate: 1.2 (ditto)
Bomber: 0.8 (the same would apply, but we all know how much we love all-bomber waves)
YounglingCommando: 2.0
YounglingTiger: 2.0
YounglingVulture: 2.0
YounglingWeasel: 2.0
I could cut the Tiger down to 1.5, but the whole self-attrition thing does cut a lot into their potential usefulness in an AI wave.
