If you have a Sovereign with the Tactician Talent (General Carrodus or custom Sov) and have them go Path of the Commander, the Tactician you already have will let you immediately start picking up Tactician II, III, and most importantly, Battle Cry. Being able to pick those up so early is very potent indeed, and seems unintended. Simple fix would be to make the talents be different but the same name as the traits from leveling so it doesn't let you do any skipping, just like custom Henchmen/Sions won't let you do so with Unit Designer traits with the same name/effect as a hero trait.
