I've run into some confusion, and would like clarity.

For the tank mounts (the bear and lion), I found a reddit post stating these requirements:

A Tankless Job I (Paladin) Complete 50 high-level full party duties as a paladin. Title: the Meat Shield
A Tankless Job II (Paladin) Complete 100 high-level full party duties as a paladin. Title: of the Stalwart Shield
But Somebody's Gotta Do It (Paladin) Complete 200 high-level full party duties as a paladin. Item: Warlion Horn
A Tankless Job I (Warrior) Complete 50 high-level full party duties as a warrior. Title: the Meat Axe
A Tankless Job II (Warrior) Complete 100 high-level full party duties as a warrior. Title: of the Stalwart Axe
But Somebody's Gotta Do It (Warrior) Complete 200 high-level full party duties as a warrior. Item: Warbear Horn
As of patch 2.2, the following trials and raids will count toward achievements requiring the completion of high-level duties with a full party: The Howling Eye (Extreme) / The Navel (Extreme) / The Bowl of Embers (Extreme) / The Whorl Eater (Extreme) / Thornmarch (Extreme) / The Binding Coil of Bahamut (excluding Turn 3) / The Second Coil of Bahamut

So to me that sounds like the high level dungeons, extreme primals, AND the Coil runs listed would all count towards the achievements.

I encountered someone who claims ONLY the primals/coils will count towards the achievements.

So which is it?
