Very interesting thread.
Attacking should be valued above defence, as that is the one causing the conflicts. With defence only the game will be deadly booring.
Obviously attacking major alliances should give multiple bonus from landing as it is far more difficult.
You should perhaps count made kills too, instead of just stolen roids. Kills tell alot how well alliance performed killing off enemies, far more better than beeing able to pick a few roids from here and there.

Second off comes perhaps covering the incoming, forcing recalls. Here alliance size perhaps dont need to count, as even a smaller inc affects your gameplay and roids kept. This will keep the top alliances score high aswell comparing to others.
Obviously crashing attacks should be calced as your good too, important kills to determine winners.

yeah perhaps some nap/political factors, but those are harder to track/calc perhaps. Agreed there regardless.
I wouldnt mind having two desiding ranks, pure value/score rank and then xp/alliance points rank. Perhaps calculate them together to get a winner.
