Now that his W doesn't have an AD ratio, what should be built on Kog'maw? I've always been super confused as to what to build on Kog'maw, as the marksman update makes him seem more AP orientated, but his builds have been wonky for me. I've typically gone BOTRK, Guinsoo's Berserker's, Runaan's, and then either PD or Bloodthirster. but with this new patch, I am just unsure anymore. What should be core on Kog'maw, and what order should I build? What's my first back, and on what item do I start being useful?
