Light for the Necromancer.

Why are the troop numbers so disproportionate in the demo? Having only 1,000 goblins with 63 cyclops seems a bit low. Also, I didn't quite understand the upgrades for both players. But I disagree that it's bad for the light faction to develop against necromancers; there are also advantages, for example, Twilight and Secrets of Light are very good, even for necromancers.
