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.
If you are going against an attack damage team or an ability power heavy team Is the deciding factor if you should Buy an abyssal scepter or a Frozen heart or even a thornmail. Graves and Leona are a great poke combo with them both being able to harass at very important times I personally hate phantom dancers on most of my ad carries because most of them do have an attack speed increase skill such as quick draw Varus passive is also a good reason more damage will make you more of a keen player as well as the guardian angel will help you survive in team fights when you get focus fired and the armor pen runes will allow you to out poke almost any other lane comp and if you feel how i do about phantom dancers try going last whisper instead
