I disagree with this. If this Ryze player is a main mid player, he'll know Kassadin too, and, because of this, know the range he has on his Q. Ryze will just farm safely, ask for a gank, and rush Banshees Veil. It'll make Kass unable to start of with Silence, and that will make it a lot harder for him. Ryze can now win a trade every 30 seconds. If he just refuses to trade when he doesn't have Banshees, it's either no trades, or trades won by Ryze. And when the jungler ganks, a Flash + W (smartcast of course) will make Kass unable to use his R to run at first. So your jungler will be able to put hard cc on Kass, if he has any.

And as that other comment said, Ryze scales very well into endgame. You became relatively tanky, with WotA, Frozen Heart, Banshees, Mercs, Rod of Ages, such items, and can almost not die if not really focused. Also because of the WotA.
