Tier list notes

Season 15 endgame lists put several Paladin oaths (Blessed Hammer Disciple, Blessed Shield, Zealot, Judicator, Auradin), Barbarian Hammer of the Ancients and Whirlwind, and Warlock Blazing Scream in the top band. Blood Wave and Bone Spirit Necromancer, Landslide Druid, and Penetrating Shot Rogue also clear Torment and the Pit. Sorcerer sits a step behind, with Ball Lightning and Crackling Energy as the usual picks.
