I don't think I would ever be the spend happy (I don't mean just money) I have a tendency to save things up in advance (Like resources: Units, spirits, etc.) and then use them all once I get a good plan in action on who to upgrade and awaken, so I don't really like to do things as I go. The one thing I do one a sort of daily basis is use my bronze and iron fodder to lvl up my newer units I have acquired to the a base lvl of 50, if I like them even more than they get CCed and maybe even Awakened using my saved resources.
But everyone has their own ways which works for them which is good, people shouldn't have to do things one way.
