These are listed as reputation sets for some reason.
My favorite is the red coloration.
The yellow one looks really nice as well. No idea yet which will be the Int mail and which will be the Agi mail.
I’ve got one plate wearer at 85 & another at 82. For Set 1 I’m really liking the gold look, very bright & shiney. Not sure that it will work for my DK, but possibly awesome on my paladin. But overall I enjoy this set.
Set 2 I’m still deciding on. Much more sinister looking.
I enjoy the green & red, but the purple looks like it works very well for a DK.
