OK, so the new balance wasn't working so perfect. We also screwed up a bit by introducing HP tweaks into strategies. Balance is a tricky business, but we're determined to get it right, even if it means annoying the hell out of you with the constant tweaks
Anyway, now all units have the same base HP (7). HP changes were also removed from Tank General and Perfect Defence, so they are now the same as before. There were criticisms that units now feel too much like the same thing, so we attempted to specialize them more. Offensive units got more attack but less defence and the other way round. Some other units are equally good at both things.
Bomber and Stealth also now have more differences. Bomber is 6/6, making it ok at attack, but it's now also able to escort Tanks and other weak units, having a very decent defence. Stealth, on the other hand, is better at attacking, but has weak defence (7/4).
Now, this new balance might still require +1 here and -1 there, but we really hope this would prove to be the last major rearrangement for unit stats.
Here's how the base attack/defence look now:
Militia 3 3
Infantry 4 6
Tank 8 4
Marines 7 3
Battleship 9 7
Submarine 7 6
Stealth 7 4
Bomber 6 6
