would be better for every two levels you get you get 1 extra energy a minute for example lvl2: 2 energy lvl4: 3 energy ... and for every factin level goes up the same should happen to the stamina + this so the creator can see
great game should give you more energy every time you lvl up, it would also be better by making a short description of each card for example: infantry a basic impirial troup very good in numbers rate up so the publishers can see this
