Further to this discussion, I had some thoughts (stop groaning!)
On Forgotten attacks worlds with no morale:
If the forgotten were to be considered an alliance, all aspects of fighting them could be changed by the POI's held by the players alliance.
For example, the Attack POI's (Tungsten, Uranium and Aircraft) held by Player Alliance could be used to multiple the attack levels of the forgotten too. Each part would have a random element, so Tungsten held with bonus of 65% would give forgotten a boost of 60-70% calculated as a random number between -5 and +5, the same for each of the Uranium and Aircraft POI's.
The crystal and tib gain by a player for attacking a fg base (not outpost or camp) would also be done in the same way - a gain of 900 000/h could translate into a multiplier of the level of the crystal gained from winning the attack (only). Same for tiberium.
Power POI's could translate into a credits multiplier for killing the fg bases. A 900 000/h boost POI level cold translate to a multiplier of the credits gained.
Resonators held by a player alliance could also be used, with the random element, to boost the defence levels of the fg, or increase morale on a fg attack world with morale.
On worlds with Morale but no fg attacks:
A similar system can be employed, but using attack POI's to generate extra resources gained from fg bases.
