well, it seems the community is split over this issue. And if I am not totally wrong, quite a number of experienced players favor single units. This might be the mere fact, that in the long run ease of play counts, not beauty.
I never had a problem with the health bar, it's pretty easy to read. And the color indication of green, yellow and red was a great tool too. Now, how are they going to implement this? I haven't seen any screenie this way.
I mean how are you supposed to know what would be the strength of that unit in a fully healed state? Or are they always the same with no more promotions based on health? That would be bad IMHO. I thought that was a strategy that distinguished level of play. For example, use of regular units versus veterans showed some kind of experience and knowledge of the game.
