A way to upgrade the teams like we do with cars and techs so that they are more reasonable currently they are so far behind that a nights sleep is worth a single click.
There has been a few time were I lose despite having superior power in all three types. Once where I was ahead by 50-50-100 (in 350-450 range) and still lost.
I want to replay it and at the same time I do not. Starting over from scratch again and again is a little frustrating. I'd recommend the different endings giving you small permanent bonuses (start with a little production, resources additional rewards from combat...)
Got the freeze on conquering bug 3 times. It reset my army, skills(which I can't rebuy unless I reset), and TS.
TS is way to hard to get. At lvl 2400 now and only have 50 of them
