Riposte isn't meant to be defensive though. It is meant to be a counter offensive ability just as it is in actual sword play.

See how it works here in dark souls: http://www.youtube.com/watch?v=DH56a4YE0Fk

Now maybe you don't want to to change it at all but just based on how it is actually supposed to work perhaps you could make some adjustments to make the ability into a 2 part skill.

Parry & Riposte -

Parry - Blocks the next enemy attack within 1.5 seconds. If successfully enemy attack speed is slowed by 50% for 2 seconds.

Riposte - If Fiora successfully blocked an attack your next attack deals bonus damage. (Could actually be a big crit on next hit if you like)
