Tbf as you said, tournaments are mostly about abuse, trying to maximize power out of each ship in a balanced settings. Very different from campaign fights.

One tactic still remains, out number the AI so it get stuck on target switching.. Yes the drone tactic got hit, but missile spam with lots of ships still works to some degree.
truth be told, fixing that will never happen, its how AIs work.
Volley tactic also work sorta, but harder with the way commands work, ships hardly ever listen
