I like Raza. Only downside is that he cant equip mont so he moves and lvls wery slow and his stones mostly depends on his lvlup so... Yeah i raly would like him to have mount.
I also tride ogre tank hero. Equiped him with dager witch gives him 3 hp for every atack, got first aid, gave shield and he proved amazing with his revenge, defence and >10 hp passive regeneration per turn.
Of course i am playing with dence monsters always, otherwise it would be no point for heroes at all
