Which race would you add to Heroes?

I saw an idea for a dwarf race somewhere, and I'm developing it (and there won't be any Orcs, hehe, the mages killed them all!). 1) Young Dwarf - Regular Dwarf (if there are more than a hundred, + to defense) 2) Raven - Ancient Raven (Ancient casts curses, both are flying units) 3) Dwarf Archer - Dwarf with a crossbow (Ranged units) 4) Mountain Troll - Stone Troll (regeneration, +50% damage from fire) 5) Shaman - Dwarf Sorcerer (casters) 6) Catapult - Cannon (Mechanism, attacks walls) 7) Ancient Warrior - Legendary Warrior
