I personally feel the changes to ground combat have made it unnecessarily complicated. Guess its time to start glassing planets instead of conquest.
Why? What is the main reason?
I was originally worried about the Logistics and Variety added for the formations etc, but now I am just thinking all the times how did I leave without it before. Of course, have a couple of improvements will help such as being able to replace the losses in one click rather than going manually over every formation.
Having only one Logistic Vehicle really simplify the all Logistic chain as well, so it is just math: how long do you want them to be able to be supplied for and the numbers are accessible.
Finally, the only thing I still cannot figure properly is the field position but that is due to lack of experience.
The only thing I would probably scrap for now is the fighters (which is pretty much now space fighters or just airplanes); that I agree to be utterly too complicated and probably just for the TN start and wars. I think we could have live without them. But again just another mechanic to learn, once done you'll be pretty much in auto mode when planning an attack.
