ASW – Alternative hero leveling.

Yes, but in this case, we will have uncontrolled OSs (which is already a disadvantage compared to controlled ones). We need to think about this.

However, these uncontrolled OSs have increased Initiative. Therefore, I would still lean towards the current approach. And it also looks more harmonious, with 3 perks for each level of machinery (instead of 3-5-1 as it is now).

And one of the main criteria collapses. (redundant connections)

Where does it collapse?

In your version, the connections go from races to skills, in mine - vice versa, from skills to races (just like to the ultimate skill). And that's the whole difference.
From a gameplay perspective, we will be able to take more useful perks in the upgradeable skills (due to the redistribution), + we will have a good choice in racial perks (due to the increased number).

Well, if you don't like the goblins' help in the racial tree, leave them in the machinery. Anyway, the Orc is separate; he has so many unique perks that it won't be possible to put them all in the racial tree.
