Ina, the cheating heroine.

I don't know where to start... So, I'm playing with a friend online, I'm playing as Necropolis, and he's playing as Fortress. The map is "Lands of Outcasts." The conditions are: we don't attack each other for the first 5 months, and we clear out the neutral creatures. He only has one Fortress castle, and a second one for income. I have a Necropolis castle and a second one for resources. I've lost to him twice already:mad:. The first time, he completely crushed me, and the second time, I almost won, but he had no magic and he set a condition: no Berserkers and no Mind Control:eek:. My army was much larger than his, but I still lost. He always plays as Inga, and he levels up Retribution, Empathy, and Battle Fury. As a result, with all the runes, his dragons and eagles deal a lot of damage. But he hasn't played against me with other heroes (yet). Now I'm puzzled - how does he defeat superior Necropolis forces? Based on this, I've come to the conclusion that Inga is an overpowered hero:smile48:. If anyone has any good counter-arguments, please respond, and also give some useful advice on how and with which heroes to defeat her with that build.
