"Now half of Corki's damage is magic damage." But... it was always like that. One of Corki's major strengths was the large amount of hybrid damage that he could put out (including the true damage from the passive). It's also the reason why he was a little trick to balance.

In that same frame, the stacking magic damage from Impure Shots was another big part of MF's strength - it was hard to itemize against her early and her 1v1 potential against other carries was scary. Also I feel Strut was the most underrated and generally usefule passive in the game. It let you get back to lane faster after backing, it let you rotate around dragon and through the jungle quicker. It also made her a nightmare for any skillshot-based champions because she was so dodgy. But it definitely was a case of invisible power that was hard to see for all players in the game.
