So.....Graves.....:/

Apparently from the information I've seen from many different websites: Graves has over a 55% win rate not only for ADC, but for jungle, which is expected, and then top lane which is totally unexpected. He is doing so well right now that his lowest win rate at top is 50%, which is against Irelia who'd you expect to kill him with her long duration stun and true damage.

I'm 110% sure he's gonna get nerfed next patch but, what are they gonna nerf to balance him without making the nerf to weak (e.g. Brand Mana Increase) or too strong (e.g. Kassadin in season 4 or early season 5)?

I don't think cool down increases will hurt him since his autos with an IE and a crit is enough to two hit the enemy ADC, which I've done before and it was crazy, and kiting is easy as since his dash CD gets lowered with his autos. Nerfing mana costs won't matter because mana is irrelevant with Essence Reaver. Decreasing his damage seems like the only sensible thing but sometimes riot goes overboard and end up overdoing or not doing enough of and you can't nerf him too hard because all ADC's need a reasonable late game.
