It seems there may be more about covert ops given the italicized faction rules in First Succession War that are stated to be in Second Succession War. Is there anything else in terms of ISaW on its way?
My wishlist:
More domestic actions and obstacles for rulers including things like long term investments for purchasing faction abilities or cancelling disadvantages, tech research/recovery, internal dynastic struggles, etc...
Issue of the 5% RP investment snowballing being fixed
More economic/production detail (maybe a portion of RP collection has to be tracked through some approximation of civilian Jumpship traffic, requiring RP to be collected and transported to factories and preventing the sudden production of ludicrous numbers of units at a single factory).
Warships
Comstar deals, interdictions, interference
If we are to indulge in being megalomaniacal House Lords let's go all the way and rule our Houses in all aspects.
