Did they nerf Hwei?

Hwei's 26.08 changes to how his ability slows stack and interact with other sources of slows had a larger negative impact than expected. While we had put in a compensation buff along with that change, it's clear after a few patches that he has ended up worse off from the change, so we are giving him some power spread between his Q and E to keep all his abilities feeling relevant.
