You just contradicted your own comment by saying

"In Vayne's case, is to continue putting Autoattacks into the nearest living thing. Casters would be Carries whose abilities comprise a significant portion of their DPS: Corki, Ezreal."

What does Vaynes tumble do? the same thing Ez's Q and Corki's R do. Its a sensical arguement. Test not using tumble to do anything else besides reposition and youll see how much of your damage drops without it.
