1. Barbarian leader can spam on exploring epic lairs with no fear of powerful enemies. Lairs should not able to be explored repeatedly, at least give it some cooldown.
2. Near all civs have overpowered ability in tier 1-3 right now, make tier 4 units less useful.
3. Infernal Grimgore should has restriction. I can usually build it and rush a tier 4 tech, like rightousness, commune with nature.
4. Dragon's hoard provides mithril? Not making sense and is overpowered. I have many ways to kill it in midgame; if I follow FoL, I can even subdue it with Yvain.
5. I seldom research smelting - iron working, because I can get free forge from that guild, and mithril from Acheron. And tier 3 melee unit sucks compared to recon/arcane/disciple/mounted line.
6. The game is nearly set if you founded a religion and build its shrine, especially Malakim. Rush Way of Wise, found the Emperyan, use religious fervor, then you can spam lightbringers, with so many free upgrades, then upgrade to radiant guard and spam sand lions, and Varn Gosam has 3 powerful traits.
