You also gain 1 second CD reduction. That 1 second is vital: your survivability scales exponentially with it.

Riftwalk is a mobility tool, and cooldown is very important regarding mobility (imagine how OP ez would be if his arcane shift had a 5 second cooldown). Until you get ~450 AP the damage dealth by riftwalk is not even worth landing on your opponent; just skim the edge of your skillshot range and harass them to death.
