Suggestion to revert the Orcs' central perk to require 3 basic skills instead of 4. Because, for example, "Art of Defense" would help a little. I would generally add the ability for Orcs to have "Readiness" in each round as a central perk, if that were possible. Let's say 500 Fury and Readiness. (just something to think about).
I don't understand. They already had that in the vanilla version, 3 branches + a racial perk. I just replaced the "Machines" branch with the "Logistics" branch for the Barbarian and the "Summoning" branch for the Chieftain. Making it more convenient to reach the central perk.
