when all logic seems to dictate a power would do best if everyone is hauling
Hauling is not everything- like I keep on saying its a balancing act where you act according to what is happening.
Ah, but you seemed to be saying people hauling to every location. I was talking about intelligent hauling.
Now, if you are saying that you can achieve all your objectives, fortification, preparation, and expansion (those that require hauling) and have time left over to do other activities, then great, it means you power has spare resources. I presume that most powers do not meet all their objectives every week. If they do, then they presumably grow, meaning they need even more resources the next week. And so on, ad infinitum, until they can't meet all their objectives.
And this is why I think PP as its designed grows to the point of stasis.
Of course, your power might say, forget that, and focus on just maintining a reasonable level of control, as you mentioned, surgical strikes and carefully controlled borders.
But what for? Nothing is won, nothing is lost (i don't mean in terms of systems, those are battles, i'm talking about the war). Powers can't rise, powers can't fall. There hasn't been a single case of a power expanding to the point where they wiped out an opponent (took control of their capital). Do the game mechanics even support taking a capital? I don't think we can know, because i don't think it can be done.
What is the point of PP as a competitive game element if in the long run there is nothing to win or lose?
As i'm fond of saying, its a never ending game of Risk. Rimmer would love it.
