Greater Rift level 55 with the Inarius set build last night. The previous night, I had used the Rathma set build to hit GR50.

The top 100 Necromancer players are using the Inarius build too. Is it overpowered? I don't think so. Why? The best necromancers only hit GR95 while wizards are at GR106 and other classes can exceed GR100.
