Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
I try to build like a tank w/ some ability power items.
I started w/ the recommended items at first but realized I wasn't getting a lot of kills and was being targeted first due to my massive ult and I would die before it even finished!
So that is why I thought tank like, I'm not saying its the best build but works for me so keep the negative comments to yourself.
I choose teleport bc its good for tactics defense and offense wise as far as getting towers. Lets face it, kills<Towers. That's where victories happen kills should just be stepping stones.
Late game items are based on a decent score and more than likely a longer game than normal (50mins+)
