Champion Cooldown Increase #1
Whimsy (W) CD raised at higher ranks.
Shadow Assault (R) CD raised at all ranks.
Playful/Trickster (E) CD raised at higher ranks.
Chronoshift (R) CD raised at all ranks.
Distortion (W), (R) Mimic CD raised at higher ranks.
This is my personal opinion on these champions and how I think they should be changed/balanced better with their current cooldowns.
I'm not claiming these need to be changed severely, but a mere 1-3 seconds for basic spells would be good enough, and as for ults 5-30 seconds.
