“Heroes of Might and Magic V: Tribes of the East”

And as a follow-up to the perk drops and the forgetful AI. I spent about 100k+ gold on Aranthir's Necropolis campaign to get the skill build I wanted – and it was POINTLESS. I didn't save and load, and I considered further respecs unnecessary. In the end, as I said before, Necromancy/Darkness/Summoning/Education experts, Attack/Logistics base, and only the Mind Lord (slow) and Necromancer's Might perks. I'm incredibly frustrated...
Basically, no patches or anything drastic will help here.

P.S. The Chaos faction is already well-known for its strength.
