Playful/Trickster change concept
One of the main problems with this ability is its overly spammable nature.
With a short cooldown, it is cancer. With a long cooldown, Fizz would be too vulnerable.
proposed change: 16 second cooldown at all ranks (up from 16-8 seconds) (new effect) Damaging an enemy champion with a basic attack or ability will reduce the cooldown of Playful/Trickster by 2 seconds. Basic attacks and Seastone Trident can only reduce the cooldown once every 1.5 seconds (They share this timer).
Now he can't just jump around in safety like a coward; he has to "play" with his opponent to get his mobility.
