Not loving them, plate is ok I guess. They could have gone way more into Norse mythology. Missed opportunity.
Gotta say I personally think these look awful and unoriginal, they are big and bulky.
I'm not seeing these show up properly in the Dressing Room.E.g. Funerary Plate is missing the helmet, has the wrong shoulder look.
Those transmogs can be used on low levels. I Have a level 43 Paladin which transmoged plate one in Heroic, Looks so amazing!
Not sure if this is known, but as of April 30, 2020 there are some major changes to how these work. First off, with Legion raids going to legacy loot early, it seems you can also run every difficulty of raid in the same week. I did LFR, then decided to try Normal. The bosses were still up and still dropped the shards. Then I reset and did heroic and it too dropped shards. By the end of my LFR, Normal and Heroic clears I had 554 shards and was planning to go do Mythic, but low and behold as Helya died, the Ensemble popped up. It just activated. I'm not sure if it was a drop or a glitch or what but I got the ensemble without ever cashing in the quest. I can also confirm two additional things. First, you don't get every armor type. I cleared on a Hunter so I got only Mail. Confirmed my other Mail users could mog to it but I do not have the equivalent set for Cloth, Leather or Plate. Second, unlike Eternal Traveller Ensemble, you do need to be 98 to mog to this now. My 40 Shaman cannot use the Mail Ensemble I just got.
