Small, Champion Feature

As I was looking at Rakan's animation for auto attacks, and how: farther away he uses his tail feathers, closer up he uses his fists. I began to wish there was a champ (that wasn't a primary damage champion), such as a support, that the closer he was to his target, the more damage he [or she] did. But not like Jayce is with different forms, just, simply range threshold- damage differential. Riot mentions many times "High risk High reward" as a positive thing. Now, if this was on a toplaner or midlaner, etc. I think the gameplay would be very toxic much like Jayce has been in previous seasons such as Season 3 and 5. Just a small detail that could be extrapolated on further, in the rest of the champion's kit such as his abilities. It'd feel pretty satisfying.
