The balance is not that great in the game, but the inferno faction is really bad. Campaign 1 and 2 are really hard, while 3 is normal again.
After lvl 17 the hero and his army are starting to be overpowered.

With summon elementals and only a few units i can beat alot of NPC/enemies.

nonetheless, a good game, even though i never played a game with so many bugs in 20years of gaming.
