Whoa this is really detailed and thought out :o. Congrats on getting leader and you're already doing a great job from the looks of it.

My only critique is that the highest power players don't need the packs as much as the lower ones (assuming they are paying players). Rewarding them points based on participation and change in contribution (say they had 10k the previous GNW, and now 12k, that could give them points based on the contribution) would be more fair IMO. It'll still reward higher level players (as they can donate more), but it still requires them to do convoy, plunder, etc, and lessens the gap in points between the weaker and stronger people.

Of course, higher stronger people contribute more to the war, but my belief is that getting ninjas for the weaker people will contribute more to the group then *ready strong player getting more ninjas :P. Just a difference of opinion, but still a pretty nice and detailed system.
