Hey Lord Naton. Again, thanks for your extensive input. Though I can't guarantee anything, I will consider some of the ideas behind these for anything I implement in the future.

Specifically, I like the following suggestions:

• An AP focused around favors
  
• Doing unique things with enovys. Maybe certain people lose the diplomatic power bonus for sending envoys to the senate, but gain other bonuses?
  
• Linking two different playstyles together so that they synergise with each other (eg. as with spiritualists and trade based economies as you suggested).
