Well, I do not have something overpowered in mind, but an AI that could mimic/answer the basic questions a human would when deciding on a move.
On the moves available for my mech, which is the move that has the best combination of :
- Defense/evasion/cover or whatever else the game has
- Hit ratios
- Can I hit a vulnerable side of an opponent's mech or can I rotate to protect mine
This is not a very overpowered idea. Now each AI pilot could have a "character" and others would opt for more defense, or others would opt to got for better hit ratios or even called shots to cause instability or things like that. That would have been advanced, but maybe more high level pilots could implement such ideas later in the campaign.
