Which Orc hero do you prefer?

By the way, Grandma's name is Garuna. And what makes her better than Krag, who, after his first attack, turns into just another ordinary hero? The vast majority of Orc heroes specialize in a particular type of unit. If you remove them, only Argath will remain, and she can't offer anything other than fast leveling. The same goes for Garuna. Even if we assume that Orcs will use a shock stack tactic, we can say that her ability won't even be needed.
