Sure, granted he got a little bit more consistent in terms of damage but I was talking about more along the lines of Peel.
Kog lives or dies based on how good his peel is... unlike Vayne/Kalista or to a lesser extent even Jinx; Kog doesn't really have a defensive mechanism to get him out of a bad spot, he gets caught and he's fucked so he is more reliant on his team than any other ADC... changing his base HP in my opinion, will not do anything.
I don't want Kog buffed, I don't play ADC but I play support... and when I am Taric, Janna , Braum, Leona or even Lulu... you know someone with decent peel, my Kog players always rape face. But if I see like a Kog with a Sona or Soraka... I know that that kog is boned.
In my opinion, as a non ADC player, he does not need any buffs or changes...
