NHF – new heroes for Heroes V 3.1.

Why are characters like Kha-Belekh included as heroes? And if so, why not make Ashu or Urgash heroes as well? And in terms of size, don't you think Kha is a bit too small? Wouldn't a spaceship be a better fit instead? Doesn't he fit the setting? And does a hero who is as tall as a titan and is put on equal footing with other smaller heroes, killing 2 peasants with a single attack at level 1, really fit in well? Especially with a subpar model that lacks any movement animation. Wouldn't such a creature be better suited as a boss in some campaign, where he would be encountered by another overpowered creature, leveled up to 30, capable of taking down a dragon with a single blow, and accompanied by armies of epic proportions – isn't this the only suitable context for Kha? Or is he really suited for weak troops, starting development at level 1, and having perks "like everyone else"?

These are the thoughts that come to mind; it would be interesting to hear the arguments "in favor" (an answer to the first question).
