so there is this solar system controlled by orks that is about get get invaded by necrons in 1 turn (invaded from outside the map) and the orks got 2 reasonably big fleets plus a space station and turrets, but one of these ork fleets is about to attack one of my systems also in 1 turn, weakening their defenses against the necrons. even though im about to benefit from such a mistake i would like it more that the orks where able to cancel their attack on my system and be able to defend their own.

my suggestion would be that if an AI faction is about to be attacked in 1-2 turns it would cancel any other attacks and defend their own system if their strength points are roughly equal to the attacking strength points.
