Kalista Mid

I'm still relatively new to the game but I've played a bit of and wonder why she can't be viable in certain situations as a midlaner.

Other ADCs have been played mid and top, Kal seems arguably easier than any of them. Dodging skill shots from slower immobile mages with her passive, shes already virtually ungankable and support CC isn't there to stop you, jungler ganks by leashing them to you allows you to save them from doing something dumb (or fighting the other jungler) or chasing down fleeing opponents, she also has that smite which allows you to steal buffs easier.

I get the whole, "Anything can work in lower elos" thing, but this seems quite viable as far as off-meta stuff goes. I'm new so there's probably something about this I'm not seeing but it seems possible.
