I have 10 minutes of internet while I am stopping over at my parents on the way to the Christmas party and I spent it reading this thread.
I agree that tying domestication into the combat system, which you devs plan on changing drastically seems like it will make it harder for you to change the combat system.
I'm also happy to see animal domestication implemented and totally dig that it would have been fun for you guys.
Please do quests next!
