Fiddlesticks
The update for Fiddsticks pushes him in an AP direction and makes him more consistent, which we like, but the numbers are wrong. You'll see a buff to at least AP ratios, perhaps more. I expect this in the patch after next.
Garen
Again, there's a lot of hyperbole that Garen is trash or unusable, and from all the data we see, that's not the case. However, he could still use a little nudge. We want to make his ult castable during Judgment, and probably a small AD ration increase on it.
Lee sin
Lee Sin has come into his own as an amazing jungler, but does fall off too early. No details on changes yet, but we're looking to add better late-game scaling without improving jungle speed.
