watched the second, some things:

mage and no essence means no mana early fights. no essence also means ..fuck essence means everything for a city. without it no shrine no mana no research no production no growth. perhaps you didnt have any city spells at first but choose first hero according to that.

i cant stand autoturn. (but i guess thats whats makes your army move after battle.)

up combat speed please. x2 works wonders for me try it.

your low power in second was you loosing your army in the first. research leatherwork to upgrade staring militia and spears.

healing pot on sov! last battle, probablly wouldnt have made a difference but you never know.

didnt look enough at your sov if you could get some enchantments on him but water 3 for reduced mana is pretty powerful.

and last a mage isnt a mage first levels hammer 15 dam and shield would have been the best since mana is scarce.

Pros: clear voice sound qualtty go at it again pls really liked it.

and 11 ais on a map for max 10 thats crazy push it down to 9 and youll do better.
