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.
More details will be added soon after I learn how to add icons.
Until then Let me basically explain that these five builds are for Ashe, Twisted Fate, Gangplank, Sona and Nasus to make you acquire your gold faster for your late game phase.
This is still in development so changes may occur.
Feel free to down-vote this guide if you think this is not viable to how you play.
