I think I know why people don't catch the new Ryze
I personally think the new Ryze is a Burst mage that relies on CDR.

or
CDR per level Glyph
Flat AP Quint
Magic pen Marks
Health per level Seal
I tried the standard old Ryze build and felt like it doesn't fit his playstyle, the DPS is lower but the burst damage is higher. And you want to abuse his R to jump infront of an aDC and burst him down.
He is squishier than the old Ryze but he does more burst damage than the old ryze. a E,Q can do about 1300 Damage in 1 cast when you follow this build.
He is almost like Annie but with a lower cooldown rotation.
