Best mid champion

strongest is akali for sure. Weakest of the traditional mid laners is probably viegar, maybe diana. If you extend it out to less traditional it's probably a toss up between lulu and karma.

Azir is just on the outer edge of being meta again. It'd just take a little push or a nerf to the top tier to put him back up again.

Ahri is not great right now. She's fine, but she's much farther down that list than even Azir.
