VERY IMPORTANT FOR GP REWORK PART II @RIOT
Release the Kraken. 
Release the Kraken. 
NOOOOOOOOOOOOOOOO DONT KILL MY CRITPLANK I REFUSE TO PLAY THIS GAME IF YOU DO.
With a cooldown of 5 on GP's Parrley50/55/60/65/70 the mana cost should be less just look at Karthus his lay waste cooldown is at 1s and cost 20/26/32/38/44 mana and GP's Remove Scurvy being at 65 I just never have the mana to use it when I need it the most if the cost was lowered it would be more helpful.
So important.
This, please this. lol
Just saying having a kraken for an ult so much cooler than a cannon barrage
