Ty bro, ive been playing this build for a couple of days and it works for me pretty well.
Check out my match history my SN is PoisonPenn

hybrid kog? smart:P U added madreds and AS for 4extra health max damage which equals 400 ap. Then you got 200 ap + attack speed to inrease with another 2 pct. You got LOW MR but decent armor and Health. Any AP carry will destroy you but if they cant come close you win. I voted up cuz it looks solid :P. I cant try it out cuz i dont have kog maw but i think ill try this when hes free:P. Gj +1 and keep up the work;3
