Cooldowns visibility on multiple form champions

Hey guys,

I was thinking about how annoying it is when playing Elise in human form, you don't know exactly when your spider form E is coming back up. While playing Rengar on the other hand, when you use an overpowered ability you get the cooldown of the base spell displayed over the actuve spell. So, my thought was, why not do this for every double form champion ? (Jayce, Elise, Nidalee...) That way you're always aware of your cooldowns.

Thanks for reading !
