I'm sorry you were not happy with the assets you purchased but I appreciate you providing feedback on what you would have preferred. I can definitely look into merging animations into one file, along with creating more animations so a character controller can be made more easily. When I originally posted these assets, they had no animations but I have decided to slowly introduce them as I make them, as I am not a professional animator this can take some time but I try to keep the page updated with what animations are provided for what object.
Thank you for your feedback. I will work on providing an update with your recommendations.
