The Cry has high morale, which is good.
However, if you level it up with a Dread Knight... that could be interesting, hmm...
But luck is still a cheat. What's the point of the Cry if, by the time you get to it, all your troops are dead (funny pun)? And you're not always fighting against a Necromancer who's leveling up their ultimate ability.
Anyway, this has already gone off-topic...
In that case, to summarize, I'll say that my favorite heroes are the Orc and the Sinister.
