[CLIENT] Nunu & Willump's abilities on the client are not up to date.
I am not sure if there is a fix on the way or not, however, Nunu's splash art and everything is updated with an exception to his abilities being updated.
This screenshot is of the old Nunu passive, with the glowing N64 floatie around Nunu. I noticed this a long time ago and today I just realized that this is still not fixed. I've already tried to repair my client.
Hope Nunu gets the Justice he & Willump deserve! [galio-happy]
