A Warrior hero from the Dungeon faction? That's absurd...

Probably, any Leto has very low chances against a Necromancer (the special ability doesn't work, and the hunting hounds' poison doesn't either). Only a very brave or very principled person would take Leto against a Necromancer. Regarding the 2 percent leadership bonus, it has already been noticed, but it seems like a really good combination with leadership, retribution, and elemental affinity, plus luck – the damage increases significantly. The fact that the troops die quickly is undeniable, but take, for example, the Furies. Before they die, they clearly manage to do more than they are worth. I often play with Iranna, and her Megara last quite a while. Hunting hounds don't die immediately either, as they can become invisible and manage to attack someone. By the way, MDANCE, I tried taking the summon skill based on your advice (although not with Leto, but with Iranna) – I was a little impressed.
