I dislike that some perks are arbitrarily bundled. For example, master chef and mining, mining and shotguns, etc. I wish there was more independence. For example, I really like to mine, but I also would love to use bows and crossbows or rifles. Similarly, my brother likes building and farming, and would also love to cook food.
I would also love LBD to come back. I agree that LBD crafting is abusable, but maybe LBD actions skills at least can come back. They're being spammed anyway, and it adds a second layer of progression, and a little bit of extra level of gamer brain fun. I thank JaxTeller for the Action Skill modlet for now.
