Felza pretty much called it. The hit to her E -> Q -> W initiate (read: shield blocks nothing) due to E's duration is pretty massive.

New skill paths aren't possible because of Q's scaling AD ratio. Now you have to max Q. Always. That removes options that were previously viable.

New item paths... aren't really a thing. Building AD? Nerfed ratios. Building tanky? Nerfed items. Pick your new weakness.
