If Kog'maw gets nerfed, he deserves it
I usually don't pay too much attention to LCS, but this Kog'maw really caught my attention. Look what Bjergsen is able to do with him every time he plays him. It's just constant poke with insane range and very low mana costs. Kog'maw is essentially a better version of Ezreal. He's able to do full damage to whoever he wants without having to worry about teammates body blocking for squishies (unlike Ezreal) And his mana costs are low enough that he's able to spam much more than other poke adc's. And let's not forget that %health damage. I'm honestly surprised Riot has allowed him to exist in his current state for so long.
has 'low mana costs'
as ADC.....Kog was not on the list.
