In the end its a closed system, and it has to behave as such.
it isn't supposed to be. and it being a closed system limited to these provided powers is the fundamental problem with it.
it serves no purpose. almost if not all of the game play around it relies on external forums and players fighting over blobs on a map with zero purpose to anything related to the mechanic beyond that. the blob map and voting aspect is basically the only thing that sets pp apart from regular bgs manipulation game play.
if that's the goal, then fdev could save a lot of effort and just focus on those two things and ditch everything else. because absolute zero people in the last 8 years have ever said that they can't wait to fortify a system (the same systems they fortified last week and the previous 300 weeks) or transport pp stuff from one system to other.. it's repeating already existing game loops that doesn't add value to the experience because the whole mechanic doesn't add value to the game if what you do is erased as soon as you stop doing it.
