Surprisingly, I wouldn't take Faideana in a game against a human player.
For example, playing as Haven, I'll retrain all peasants into archers, leaving one peasant. With his ability, this mega-hero will only kill one peasant...

Anven and Gilraen are indeed powerful. Ossir and Wingael are the best starting combination.

Talanar – if you read and analyze it, it seems very tempting, but testing it in practice showed me that the hero is practically the worst. At the same time, it's the best option for a secondary hero (very useful for gathering troops, easy to get reinforcements of Dancers).
