Well I just want to add that while Minato and Kakashi had legit reasons for not being able to master elemental rasengan, but what the actual fuck was Jiraiya doing the whole time? He already mastered rasengan when Minato was alive. And he had already mastered elements such as katon by that time. So why did it never occured to Jiraiya to use his left hand to supply the elemental chakra?
