The nerf on Riftwalk, it's real.

If you spend 4 seconds in your first Riftwalk, you won't be able to hold a second one for three seconds.

60% movespeed for three seconds is so clearly inferior to Rammus's Q or Hecarim's E (who both ramp up 75% over a few secs and keep it for another few secs), it's not even funny.

Also it looks like Kassadin can attack while phased out, so really, I think there's stuff that's seriously wrong about the new ulti.
