Won't Nimbus cloak bust kogmaw, Kass, Diana, etc...
Basically anyone with a low cooldown ultimate...
Kog'maw goes from being an immobile champion to someone with a 100ms boost on demand.
Good luck ever escaping from a Kassadin or Diana or Akali again. Good luck ever catching a Kassadin again.
Not quite sure what the huge thing is with changing all these effects to be "whenever you use your ultimate". Like Zeke's, and now this? There's such a huge disparity in ultimate cooldowns, it seems like a difficult balance mechanism.
How is a champion with a long ult cooldown like Karthus ever going to feel good about anything that occurs only on ultimate use, when champions like kogmaw have an almost non existent cooldown?
Does udyr get the bonus whenever he uses R, or does he get entirely locked out of all of these things too?
