As long as there's a way to push Brand back into mid instead of "support", then I would be happy.
Cait's traps needs higher cooldown or some restriction, cz she's now zoning way too hard.
Camille needs some hard-nerfs with her numbers, especially her ult.
Ivern is eh to me as well. Not sure the hype about it.
Rengar's Q needs higher cooldown at early game, because as a top laner, it's a very easy ability to spam at your face like Yasuo's Q.
Ahri's bonus movement speed at her Q needs to be removed. Like why is that even a kit.
Same with you on Syndra. Her point & click ult is just too toxic.
These are all my opinions for the champions you listed, as a saying that your bans aren't a joke. I dunno bout Hecarim, Graves & Orianna doe, as all of them in my games just sucks hell.
