Katarina's Killer Instincts, LeBlanc's Mimic, Renekton's Fury, Karma's Mantra and Rengar's Ferocity... it wasn't Karma's mechanic to start with.

To be honest, I'd say that Heimerdinger's original ultimate, Shyvana's Dragon's Descent and Quinn's Tag Team are all essentially the same thing too. Their abilities modify/clone/empower their standard abilities - either for a duration or for the next one cast.
