This may not be a bug, but if you were to follow the rotation given each class has 5 sets, Headrig’s Gift should match Season 22. Instead, it matches Season 23:
On PTR S27 Awards:
Wrath of the Wastes
Roland’s Legacy
Unhallowed Essence
Raiment of a Thousand Storms
Bones of Rathma
Helltooth Harness
Tal Rasha’s Elements
If it were to follow established rotation, it should be:
Horde of the Ninety Savages
Aegis of Valor
Gears of Dreadlands
Patterns of Justice
Masquerade of Burning Carnival
Mundunugu’s Regalia
The Typhon’s Veil
Bug or intended? Upon futher looking at the history…
| ROTATION NUMBER | Barbarian | Crusader | Demon Hunter | Monk | Necromancer | Witch Doctor | Wizard |
|---|---|---|---|---|---|---|---|
| 1 | Might of the Earth | Thorns of the Invoker | The Shadow's Mantle | Monkey King's Garb | Grace of Inarius | Raiment of the Jade Harvester | Firebird's Finery |
| 2 | The Legacy of Raekor | Armor of Akkhan | Embodiment of the Marauder | Inna's Mantra | Pestilence Master's Shroud | Zunimassa's Haunt | Delsere's Magnum Opus |
| 3 | Wrath of the Wastes | Roland's Legacy | Unhallowed Essence | Raiment of a Thousand Storms | Bones of Rathma | Helltooth Harness | Tal Rasha's Elements |
| 4 | Immortal King's Call | Seeker of the Light | Natalya's Vengeance | Uliana's Stratagem | Trag'Oul's Avatar | Spirit of Arachyr | Vyr's Amazing Arcana |
| 5 | Horde of the Ninety Savages | Aegis of Valor | Gears of Dreadlands | Patterns of Justice | Masquerade of Burning Carnival | Mundunugu's Regalia | The Typhon's Veil |
The rotation has gone as follows:
S5: 1
S6: 2
S7: 3
S8: 4
S9: 1 <— Necromancer introduced
S10: 2
S11: 3
S12: 4
S13: 1
S14: 2
S15 : 3
S16: 4
S17: 1
S18: 2
S19: 3
S20: 4
S21: 1
S22: 5 <— New sets introduced (but skipped Rotation 2)
S23: 3
S24: 4
S25: 1
S26: 2
S27: 3
So perhaps this is a self correction and the new sets won’t be Haedrig’s Gifts until Season 29.
