I don't have a useful suggestion at present, but I'm thrilled to see that you guys are thinking about this. Transports, as it stands, are sufficiently powerful that conducting any offensive strike without them is completely silly. Load up the transport, roll in, pop guard posts or command post, roll out. This makes for a lack of diversity in offensive action, undermines the effects of the varied new guard posts, and just feels kind of cheap since the AI doesn't even have transports. I think if you could achieve all six of your goals that "cheap" sense would go away, and that'd be great. Smiley
I'm not sure the 3.184 changes at present will get us all the way there, I'll have to test it but my guess is I'll still always be shipping offensive units in a transport every time I attack a planet, I'll just have to offload them a bit further away from the target command posts and guard posts.
