Method and season context

Assumes a mostly isolated target and a complete encounter. Sustained single-target contact, survival and a plan after the first burst outweigh pack-clearing effects.

These bands are a qualitative QuestBase editorial judgment for Season 15, not a timed benchmark. A, B and S are relative to this activity and the stated assumptions. Use the linked build's limitations to decide whether its position applies to your character.

S tier

Strong activity fit with a relatively clear route to its main advantage.

Rapid Fire RogueTrack the boss through the whole volley and reserve movement for mechanics rather than for style.Bone Spirit NecromancerKnow the boss's predictable animation, keep enough resource to execute, and use control only when the target is susceptible.Hammer of the Ancients BarbarianSave crowd control and defensive tools for the boss's safe damage window, then spend the stored Fury.

A tier

Capable when its setup and player preferences match the activity.

Zeal PaladinSave movement for the return after a hazard and assess full-fight contact time.Landslide DruidLearn the boss's stationary windows and move only when the arena requires it; do not build the entire plan around pack-only control.Hellfire WarlockBank the active-bar preparation for a known safe boss window.Charged Bolts SorcererMeasure contact at a safe distance and do not force maximum overlap through boss hazards.

B tier

Playable, but a specific limitation demands more effort or gear.

Whirlwind BarbarianBring a repeatable generator and defensive window; measure damage during the full encounter rather than the opening spin.Pulverize DruidPreserve a defensive response for each approach and check whether single-target damage persists between major hits.Penetrating Shot RogueUse a repeatable direct-hit plan and confirm the boss can be hit reliably from a safe lane.

Who should use this list
