Riot why everytime you Nerf Corki it always has to be the R?

What is Soo Wrong about his Ult? Why don't you guys nerf his E or Q,W? Why is The ultimate always the most hated one by Riot? The ultimate is Corki Identity.

Patch: 3.13 Missile Barrage Base damage reduced to 100/180/260 (from 120/190/260) Cooldown between missile shots increased to 2 seconds (from 1.2) Cooldown between missile shots can no longer be reduced by Cooldown Reduction (Cooldown Reduction still affects how quickly you gain missile ammo)

I love AP corki, Nerf anything else besides his ult. Make him an AP/AD caster not an ADC.

His AA hurts alot because of his E, He shreds someones armor and MAgic resist and just AA once . His R is not the problem its his Build patch and E.

And then Riot answer is gonna be if you want to spam R go play another champion.

Who in the game has a 2 SEC linear long range poke other than Corki? That actually does decent amount of damage.

Corki is the 2nd champion after Cass who has an identity Crisis, People who want to spam R and assassins corki.
