After reading over Rarek's thread I thought of something that would benefit everyon - potentially - however only really have an effect at higher ranks.

Repeatable mission: Ambassadorial Gaurd.
10 rounds at X energy / comletion:
chance for 1 political favor per round, garunteed 10 political favor on completion.

OR

Daily Mission: Securing the Summit
10 rounds at x energy / completion:
1 political favor per round,

A battle market "artifact" that could be bought with political favor
political funding : 10 political favor
reduces the cost of invasion / colonization of a planet by 10% down to a minimum of 10% colonization / invasion cost.

Friends in High Places : 30 political favor
Your high profile contacts have given you some extra manpower, +20% planetary production for 1 day

i like it but it might be overpowered if it can stack with everything that already boost production. ( planetary rings, summit contracts,Klorvis Supply Conduit ect)

The extra boost to production would be very overpowered when used on a suped up rift I think. But the first idea about reducing costs of invasion is alright, I mean I doubt many people will really use it, but it's there if you want it I guess.
