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.
This is my build for Heimer, i don't really expect anyone else to necessarily use it, but i like to have it so i have something to refer back to. So if you don't like it i'd love to hear why, i am far from a expert and just enjoy the game for what it is, a chance to play a game with some friends with the best price tag there is, FREE!
