Unfortunately, it looks as though Army 2 is a good deal better than Army 1. Firstly, Army 1 is mostly melee. This will give them great trouble killing of the three squads of Warriors of Ashra. With the elven women as a screen, Deathwalker 9k will have plenty of time to blast through the tight packed orcs and romans (who are without a bonding hero!). I think the Airborne Elite will be more of high-powered snipers than grenadiers, taking down Army 1's range. Ne-Gok-Sa and Isamu will probably be hanging in the start zone, drinking beers, eating chips, and watching a game on the TV.
Of course, luck could cause the game to go the other way, and Army 1's Deathwalker may be able to get rid of quite a few Ashran's early, so the battle isn't for sure, but if played right, Army 2 (surprisingly synergy-less) should have an advantage.
Looking forward to it, and the many battles to come!
