I'm not a high ELO player, I play for fun, although I do enjoy an occasional ranked. Add me in-game if you like my builds - I would love to play a game with you.
With the tentative changes on the PBE (here), my Teemo guide will likely need a good reworking.
With this being said, the removal of Malady and changes to Wit's End and Nashor's Tooth will make the build much more interesting.
I am currently planning a new item order and build that will function pretty much the same as my current build, maybe even stronger due to the item changes.
