The Price of Love

I started playing, but I hit a dead end on my first try. I wasn't ready for that blue army to appear. Here are some preliminary observations. Yellow and green – these are strange characters. Their behavior and the spells they use are odd. These heroes don't attack castles, they don't engage the main hero, they just hang around and hunt my weak heroes. The green hero didn't disappear even after a week, even though he was left without a castle. The yellow hero appears so unexpectedly and so close to his own castle, blocking access to it, that I had to restart the game to get at least one hero to defend it. That's not good. (I don't want to be distracted and have to send the main hero back just for such a minor thing.) The main one who suffers in this situation is my brother, the gnome necromancer. I can't afford to lose him; he doesn't really have an army, and there's nowhere to retreat to. The place where he appears is a real trap. Something needs to be changed in this setup; maybe add a safe haven. I don't like hybrid heroes. I just can't understand why a gnome needs necromancy. There are three castles, enough for several heroes, and I don't see the need for raising the dead. It would be better to give him "dark magic" and "sorcery" from the start. I saw a lot of "dark magic" spells in the cursed castle; I don't know if it's just a coincidence or if it was intentional. I think that will be enough to defeat the blue faction.
