I really appreciate the effort and what you are trying to achieve.
My biggest issue with this setup is: There is not much to spend stamina on that is worth it. For the Combine promo the TS event for sure but it has an annoying 6 hour cooldown after only 5 attempts. And UL... Well you know the problem with UL. Its no fun to spam stamina to not get anything you need 99% of the time. You open pack after pack and its a disappointment with some very rare happy moments (aka banners). It is just no fun to only pull useless stuff you 100% don't need anymore.
