The set you could always wear or transmog?
Rift Stalker set I am wearing now.
Frostfire Regalia
This one (Vestments of the Purifier, mythic).
Runners up: Vestments of the Seven Sacred Seals (all difficulties), Frostfire Regalia, Boneblade Battlegear (mythic), Battlegear of Guiding Light (mythic).
Warrior T3. I’m still missing the chest and legs though.
This one. Pandaria shaman challenge mode gear. Initially I hated it on my Draenei shaman that I earned it on, but I love, love, LOVE it on my Dwarf.
The Kor’kron shaman gear from SoO is a very close second.
Behold what I am currently wearing!
This one, I like yellow and lights
Pretty much all T5 and T6 sets with a few Ulduar and ICC sets mixed in. After that everything is pretty blah even though I still collect them cause Gotta fill up those logs with everything!
Any tauren druid in Tomb of Sargeras or T6 deserves a hug. It’s the most fitting race/armor set in the entire game, excluding heritage armors.
Valorous Bonescythe, because there is just something about the Black and Gold and how it all completely meshes.
The paladin judgement set has always been my favorite… still after all these years. That set is badass.
I’ve literally been wearing this set on my mage since MoP
And on my demon hunter i usually default to this, but i so tire of red. I want to get my hands on the mythic antorus set.
Vestments of Winged Triumph, any difficulty, from Siege of Orgrimmar.
…just gotta turn off the helmet. (Or mog it into the crown from Hyjal or Tomb of Sargeras.) It might look passable to cool on belfs, space goats, humans, or dwarves, but it looks utterly ridiculous on my tauren noggin… Le sigh.
yawn…got some work to do…
Judgement and/or Champion plate
Well, kinda likin’ the Bloodwake pieces I’m using now.
The Acherus Knight set is always a classic, like comfy jeans.
A huge fan of the Darkshore Horde set.
Fel Iron plate set and the red and black recolor of it. And the sets that look like my current mog Exalted plate, wish they had them in more colors.
