PP is all about friction.
- Friction between differen bonuses, leading to increased profit when doing inter-power-trading.
- Friction between commanders, when competing for different PP tasks.
- Emotional friction, when players of different powers identify with their power and roleplay this devotion.
It is not necessary to concentrate exclusively on PP - indeed, it is not recommended, in my opinion.
Fulfill some PP duties while trading (or trade while helping your power, if you want to focus on PP more). While preparing a system for Antal, I earned more than enough money to purchase a second delivery. This speeds up my rank progression and I still have some credits left. ( I fly a Trading-Python at the moment).
But, for heaven's sake, why would anybody sit in front of his computer, waiting on these deliveries to refill? If you do so, it is completely your own fault and I am not surprised you find PP boring.
Easy solution: don't do it! Hunt for bounty, trade, whatever you liked before PP was launched. All this is still there, waiting for you!
Oh, did I say that I like PP?
