I think some balancing may be done, but you CAN have a bunch of hunters/troopers/Grenadier pretty easily... And they are easily destroyed.

I mean, you already begin with a huge force, may be able to capture more points in less time than your opponent. If you already have siege weapons, you may even make him unable to develop, being shot down by a barrage of fire...

The dragon issue occurs, but not so much. In multiplayer, the IA should be improved to use anti dragon units a little bit more and capture points quicker. Having a large force and turtle is bad, for the AI too.
