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.
My experience with yorich
I always thought Yorich was a bad champion but this week's champion rotation allowed me to try him out. He is now my favourite top laner, decently tanky and all of his abilities complement each other. I recomend this chapion to at least be tried out at least once and you will probably like it
