[GAMEPLAY] Nocturne "E" Movement Speed

According to http://leagueoflegends.wikia.com/wiki/Nocturne Nocturne is suppose to receive 335 movement speed from fleeing enemies. Currently, he receives like 212 movement speed which I find weird since it is a random number. In addition, even if this is not a bug and Nocturne is suppose to be receiving 212 movement speed towards fleeing enemies, celerity is not working properly with Nocturne's bonus movement speed from fleeing enemies. Currently he is only gaining about 10-11 attack damage when 8% of 212 is 17. In the masteries tab in game, you can clearly see that while Nocturne is moving towards fleeing enemies, he gains the 17 attack damage, but when you go look at Nocturne's stats tab where it shows ability power, movement speed, etc, he is only gaining about 10-11 attack damage.
