Haven discussion.

Well, what can I say.
They are obsessed with defence. They practically never put points into Spellpower and knowledge, and they don't mess around with attack either. Units are cheap, but peasants are objectively expensive. 22 gold for these fellows is simply indefensible. Even +1 gold per day won't solve it. Waiting 22 days for this miracle to pay off...
True, for one hero they bring +2 gold and he also starts with Recuirement (increased growth for levels 1-3).
The optimal hero for the game is Christian (Kei) because he wipes everyone out thanks to his specialization in Ballista.
Holy Charge hits hard. Sometimes even harder than a fireball. So Ballista+Charge is just what's needed. I didn't check the training prices, but it feels objectively expensive. The griffin upgrade simply pulls the rug from under your feet—6000 gold for level 4 is steep.
On the other hand, the cheapest level 7 unit is the Angel: 10000 + 15 ore.
