ASW – Alternative hero leveling.

However, these uncontrollable creatures have increased Initiative. Therefore, I would still put an arrow there. And it also looks more harmonious, with 3 perks for each level of machinery (instead of 3-5-1 as it is now).

And with the arrow, they will also be uncontrollable. But if you strengthen the catapult, the choice with the creatures might shift ;)

In your version, the connections go from racial to skills, in mine - vice versa, from skills to racial. And that's the only difference.

The point is that they are already almost like the next levels of skills for the racial units. In your case, you will have to additionally level up the skill of both the racial and non-racial unit, but in my case, you won't have to level up an additional racial skill.
