[Gameplay] Kennen - Not really a bug more like a description fail

Actually I've known this description fail on E "Lightning Rush" for quite a while and would report it on the changelogs ingame but i can't find them anymore.

The description itself says "Kennen gains 335 movement speed" which is basically wrong - his movement speed is 335 but he doesn't gain 335 on activating E - I sadly forgot how much it really is but I just wanted to say it since its in for a season or such and wasn't changed what really is no problem.
