Swap Wanderlust And Heroic Trait Costs
If you pick premade human race and start rolling XP, preestige and arm your champions and henchmen to the teeth the key is the ability to purchase more quest maps. However, should you consider how relevant Heroic trait is without Wanderlust you would soon find out that the trait cost for Heroic trait is simply too much to think about. For custom factions Wanderlust is then again way too cheap. It hands not only essential endless stream of quest maps over until you hit the Mana Blast / Shield, all the fancy quest-equipment and viable "training camp" for troops during peace but also a very useful leather armour for early turns.
Therefore Heroic should cost only 1 point and Wanderlust 2 points. The premade human faction would not change due to zero-sum addition.
