OK so far very good a lot of people have already shared most of what i was going to say so ill just say one thing for now.
planetary invasion:
with two transport ships and about 3 guardian MK 3s in a fleet (if that effects it)
the plant pop was 5.5 billion and i was attacking with 5 billion men
the advantage on my side was 222 compared to their 22 this is the first thing i think is an error
(i know the invasion mechanics are not all in) but just to say invasion should be by default advantage goes to the defender
also the population that where left 0 seems i had killed everything that lived (who am i Joshua?) really think genocide shouldn't be the default maybe an option ( lol if taken out of context ) i will test what happens with less men invading.....indeed attacked with 0.8 billion on a plant of 4.6 and got an advantage of 281 to their 16 and killed them all.
Guessing invasions are still under work still i hope his helped
