Indeed the two initial factions were unbalanced but I helped make it a bit more balanced by weakening a bit of the Swordsmans attacks, and making it a bit more costly to get them out. I play tested it myself and found it a bit more easier to win as the Magic, but it still is challenging cuz of the AI's speed in procedural commandeering. (Pull up log 1 under config to see what I mean, as you play you'll see each and every command and order being made on the other side.)
By making these changes the Tech AI works a tad slower as it has to wait for resources to stack, then they start building the army.
So as it lays out right now, the Tech are now harder and take longer to get out, BUT they are still stronger then the Magic when it comes to firepower. Just as well, the Magic are easier to get out, but are harder to utilize what they are really meant for thus have little firepower... at the beginning anyways >=D
I'll put it up as soon as I make a few more changes, I'm giving the structures more defense cuz I find that they fall rather quickly.
As of now I've yet to find out how to change up the AI's construct, whih leads me to believe it's within the code source of Glest. Also meaning I need to learn C++ first. ANYONE else may have a crack at it if they wish.
