Karma is cancer
I know her late game really isn't that good, but honestly it doesn't matter. This season is all about laning phase and Karma is by far the best in that regard. She has the best poke of all supports, and it's almost to punish her if you catch her out (thanks to her ms boost and shield). And if you manage to get close enough to her she just roots you and walks away. Someone please tell me, how are you supposed to win lane against a Karma? You don't.
