I think MF scales pretty well nowadays tho, especially if she gets her ult channeled. Anyways this is why I appreciate both Poppy, Malphite, and Nautilus vs those slippery ADCs. Point and click hard cc, tanky af, gap closers to deal with kiting ADCs, and can solo the ADC in some scenarios. To a certain degree Taric, Rammus, Maokai and Pantheon as well. Deadman's, Frozen heart, and Randuins help (#MakeRighteousGloryGreatAgain). As far as Kalista goes, her damage does fall off slightly as the game goes on, since her damage comes from stacking spears and isn't upfront like Jinx. Other counterplay options such as Assassins. Besides, Singed shouldn't be able to run over every ADC anyways.
also add me, DocReverb, best Karma, Jax and Yasuo player in this thread. By far :^)
