ASW – Alternative hero leveling.

That is, give all races, except for Orcs, a dependency on racial abilities, but that would be uncouth.

Everything is fine. Because in reality, there won't be any dependency on race, and this connection will be invisible. After all, racial abilities are implied for all heroes, right?

Because in RPE, this isn't a base element.

Not in RPE. It's in the original resources. Yes, it's not a base element. But why do you assume that the base won't work exactly the same way? Orcs aren't specified, so they won't be there.

But if we're talking about aesthetics, I would prefer to see perks like mass acceleration, mass skin (and spell luck) not on the first level. And it's also too much. Even in a weak attack, mass acceleration was only on the 2nd level, let alone a strong attack.
