HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

The hiring cost, weekly growth, and upgrade cost are 42090, while the alt-upgrade cost is 28710. The Guard costs 25, the Legionnaire 250, and the Landlord 25.
Faith Guardians (145) and Justiciars (210) are more expensive than Zealots (130).
It would be good to adjust the cost.

Regarding the Legionnaires, isn't there a huge difference between the Legionnaire and the Guard with the Landlord? The cost of 2.5 Assassins is designed so that you can't buy many of them and to avoid balancing the growth and strengthening the Landlords.
Guardians and Justiciars are damage dealers/support, which is why they have this cost; they are more valuable than Zealots in a rush, but not much worse in defense.
