Good points, the main reason is that I originally just made this as a reference for myself when they took out custom item sets, so most of the differences were just my item choices.

E is a powerful utility, but I've always found it too mana-consuming, which is why I've always relied so heavily on W (in midlane as well because of the % damage), and Q for the passive attack speed as well as poke and defense reduction.

I like having heal because of how squishy and slow Kog is. Ignite is my second choice, but I hardly ever do since most people save a pot for it.

The masteries weren't changed because I copy/pasted most of them. They'll need updates now that the rune system is changed, but now that item sets are back I probably won't be updating this build again.

Thanks for the input +1

Actually how it is now will only stack up to max attack speed after 6 stacks of Ginsuoo's. Sometimes having other boots - such as sorcerer's if they're building MR or Swiftness to help out catching people with your passive - will definitely help but in most situations I stick to the classic greaves. I wouldn't recommend putting so many AS items into one build, so if I were to build BotRK, I would take out Trinity. I'll make sure to mention that in the guide :) Many people will find different things suit their playstyle better, though!
