I feel like if one were to go this way, changing the officer level to 4, removing +1 elite skills from Officer Training, and leaving AI cores alone might be a more restrained approach. I'm not sure I'm sold on it, though, though I understand the rationale.
*Are* fleetwide skills actually stronger? I'm not sure that "how many Ordos can this take down" is a particularly useful metric for this. I mean, if that's the metric, then sure, we can say one or the other is "stronger" by that metric, but an endurance fight like this distorts a lot of things.
What about something like, "how easy is it for an average player to take down 1-2 Ordos"? I feel like the skillset required for creating good AI ship loadouts, understanding both your and enemy AI, understanding the tactics to use, the orders to give - that seems more difficult to figure out than than learning to pilot a ship reasonably well while your fleet just kind of does its thing (yeah, you need to make some reasonable loadouts doing that too, but not to the same degree). And, with a smaller fight, your personal impact is magnified.
Another thing to consider here are the Omega weapons. You can certainly make AI loadouts capable of using them well, but the player would still get more out of using them personally, and they're quite the force multiplier.
