What I believe would be a better skill tree is to remove basic skills like unlocking new skills to new areas of the skill tree. Once removed, add new skills for better character build up for player unique build up to thier style. Then have basic skills and unlocking areas of the tree to be lv base to learn the skills like "lv 2 you unlock construction, lv 3 be cooking, lv 4 hand to hand combat, and the basic skills to build when unlocking them." This will help add more skills to the tree that could better the players character stats and bonuses like more meele damage, range damage, poision/explosion ammo, stamina control, and etc. Also beastmaster basic if attained through lv base, just up the taming, breeding, riding, and sneak to lv 2 when you learning beastmastery basic automatically and up to 5 when maxed out on beastmastery.
