What if Caitlyn was turned into a mage?
By giving her Q and R an AP ratio.
Let's be real, her playstyle can't really work in this meta. Her huge mid-game trough allows assassins and the new juggernauts to just run her right over.
In the games she does win, however, she's incredibly annoying for her opponents, simply because she'll right click on you and she has more damage than you, so you have to stay out of her big zone.
I get that being oppressive is part of her theme, but focusing on her spells and putting her in perhaps the mid lane could be refreshing. Who knows how it would turn out. It's much more fun playing around her traps, blocking her ult, dodging her Q than it is just staying out of her auto range.
