First thing I'd like to get off my chest: Giving Missions to pirates is awesome. It's just fun. I am, however a bit concerned if it's not a little bit overpowered. Yet, for a 1000+ pirate fleet, your probably need to hold the upper hand anyway.
What I wonder is, when do pirates retreat? I seems to take kinda long for them, after the job is done (bombarding planet), to either attack anything else in the gravity well (if at all) or leave it. That's annoying if you want to colonize the planet (still nice to steal planets from AI allies, like the one with artifacts).
The way your standings with other factions are presented is very confusing. I noticed several things here:
Sometimes a pact significantly lowers or raises your standings. Regardless of wether this happend or not, pacts are often canceled immidiatly again regardless of sufficient mutual affection It kinda seems to me that only the envoy bonus really counts when it comes to determin wether or not you can agree on a pact with another player, although the interface makes it seem like you can. Possibly a bug here? I often need a much higher standing than displayed to enjoy the benefits of this expansion
I really love the new features, yet, they seem still to be a little buggy and/or confusing. I will continue experimenting with them and post results here. If anyone could confirm what I assumed, that would nice too.
