As someone who owns EVERY teir set (minus T3), and the pvp sets...this is bar-none the best looking set. I think this actually rivals paladin judgement set. And to me, that's saying something.
As for the meaning, I am inclined to agree with the Benedictus story. I admit I am loathe to again watch some random npc get fame for redemption, but it's blizzard. I also think there is meaning artistically. For several teirs, they seem to have kept trying to get flashier and flashier. In this final teir, They seem to have taken a less flamboyant but still powerful approach to it, and it works well.
