This shoulda been the Paladin tier set.
I bet he was supposed to play a big part in whatever content was supposed to be in Vakthros. No way they had it feature so much in promo material & the cinematic for it to have not been planned for anything.He's a major character in DF, he appears in the first cinematic and helps you in the first raid, and then does nothing. His story in DF was kinda dropped like lots of other stories and characters this expansion, DF is a mess.
