Just randomly popping in about the turning thing. If I am understanding the sentiment correctly, people want to see fleets turn on a dime instead of propelling themselves in wide arc? But if I understand the developer's sentiment, they want the ships to maneuver for combat purposes. So would a happy medium be to use a trigger similar to the one for the strikecrift build rate on carrier cruisers to determine whether ships use 'normal maneuvering' or 'combat maneuvering'? I.e. if no enemy ships are in a gravity well the ships simply turn and go to the intended target, otherwise they behave as they do currently? It is probably a minor issue though. Heck, toggling between types with the sudden appearance of enemies might lag the game a bit. Perhaps a job for a modder rather than the developers?
Personally I'd like to see further tweaks on pirates. It seems like Diplomacy basically killed the pirates due to them being far to OP and determining the course of a game. Somewhere, lost on these boards was old suggestions of mine about refocusing them on econ disruption rather than military conquest that could destroy starbases better than pre-late game fleets. Basically, their advancement needs to be slowed significantly so that players can keep pace while dealing with empire and fleet expansion. 250 credits shouldn't be able to purchase a crack fleet able to bust up a planet. That said, the idea of dumping thousands of credits into a big raid in the later game is just fine. At least if each pirate ship isn't stronger than a level 10 capital ship.
And just because it hasn't been mentioned in a while, some love for the Antorak Marauder's Subversion ability to make it worthwhile would be nice. Maybe with a longer duration and the ability to steal some income(or negate the target's trade income!) it would become quite useful. That or forget the stolen income and give it range equal to a TEC's Sensor Probe (at least at level 3). Obviously stacking and other fixes for other capital ships would have to come first though.
Overall the changes look good, and I am glad to see continued support for Sins.
