I feel like Riot doesn't even play their own champions.
Lately I feel like champions are balanced without having enough knowledge about their gameplay.
I'm talking about this:

On a separate note, we cleaned up a few** weird numbers **in Kennen’s other abilities_
probably talking about:
MARK DURATION 6.25 seconds ⇒ 6 seconds
WEIRD NUMBERS? There was a reason for that. At max rank, kennen was able to "chain" his W's thanks to that 0.25s, because his W has 6s CD at max rank. His passive used to last 8s, so he had a bigger window, but riot decided to nerf it without completely removing this chaining mechanic by giving him 0.25 extra seconds.
A lot of kennen players max W in the top lane, since it greatly improves your harass, wave clear and AOE damage.
In the same patch, they made some random changes to Viktor. Changes that make him feel clunkier, too.
Edit: for some reason people didn't get the point, I get that this patch was a buff overall, what i'm trying to say is that riot (or maybe just the guy who wrote the patch notes) doesn't really know their own Champions. Also, did everyone forget about AD kennen?
(Protobelt, no icon for that yet)
does that even matter all that much?
or
