Sorry if some of these have already been addressed. To me it seems better just to make a list of feedback points rather than hunt down the existing posts that talk about (or don't) the same issues and post "I agree" on those.
The new patch really helped out entrenchment I think
The gravity well support on the starbases really make them a force to be feared. Once you enter a place with them you need to either run out right away (so the exit damage won't kill you), or kill the thing. > however, I feel that you may want to scale the damage based on the number of upgrades the stardock has. So when its a new baby stardock, it only does mayb 10% damage +50% exit time, but when its a fully upgraded stardock maybe does closer to 40% damage and adds like +300% exit time.
I feel like starbase features should be linked to their counterpart tech (repair bay = can build repair bays in starbase, trade ports = can also trade ports in starbases), because to me as it stands, I feel like I should then ONLY research the starbase side of it and use only starbases. its like "why spend the extra 400 credits, when I could save for another starbase in this region and not use up my tactical slots". However if say, 'repair bay' unlocked both in base and out of base, I know I would end up 'building' both in some systems anyway.
Or you could just go back to the old way. I liked the "you can't build trade ports in starbases until you have researched normal trade ports" idea. I know it didn't seem work before for some glitch or another, but if you could somehow make it work (so there is like a subtle trade tech tree between the different windows) then I think that is best.
The change in time based on who owns the gravity well is definatly a good move. It reduces the vesari starbase fighting I was doing with the last patch (I'd run in, build a starbase outside enemy turret range, then use the starbase as my main offensive)
I still feel that range for stationary starbases should be increased, but the natural phase jump inhibiting might make up for it.
When somebody is in cinimatic view, and they press alt to see advance attack radius, names, and all that. it should also show the things that were turned off by being in cinimatic view. (the emblems for example, when I want to quick glimps out of cinimatic view to see if I should be micro-managing my fleet or not, I need to know which ship belongs to whom before the health bars mean anything)
There should be 'destroy a starbase' missions given by other players, rather than tactical structures or ships. (if this exists I'm sorry. The AI has yet to ask me to do it.) It may even be better by giving the location of the closest starbase or one most important to the person giving the assignment's goal. A mission could be "destroy starbase at planet exampleis" and I think that would work well enough provided that planet could be reasonably reached by the player recieving the mission.
(nit-picky) The Advent starbase explosion looks grand, but it seems to short (like it explodes and disappears very quickly and it doesn't feel nearly as epic as even some capital ship explosions). Making the explosion last longer would fix this
(nit-picky) The hit locations on the TEC's starbases' shields are too lined up. I know this is because its on the corners of the shield, but when a bunch of bombers go in for an attack run you see the lines too clearly, (it breaks suspence of disbelief) if possible on the big broad surfaces like those shields, try to see if you can somehow set the targeter so they don't always form a perfect line. Regular shots seem ok and spread out enough, its mostly laser fire that lingers for a few seconds (maybe they won't be allowed to fire at any 3 corners that are aligned, they would focus fire on 2 of them and the 3rd shot would have to go with an un-alligned location)
(nit-picky) Missles and lazers being fired from the side or behind of an advent defence vessle should not target the front tip of that advent defence vessle. It looks silly and dumb ("Which asshole is firing that gun", I asked "that is like the smallest target of that ship")
