I'm really liking Fabulor's current look. It's everything I look for in a transmog set - big anime stompy boots, a maximum of two pieces from any one set, and a huge variety of pieces from a wide range of sources. I feel pretty good that I probably won't run into someone else in Pandaria sporting the same look.
Bright red and gold are clearly the primary colors, but copper/bronze and dark slate grey are strongly represented in the boots, gauntlets and shoulders. The shield is intentionally small and lightweight - Fabulor IS a healer, after all. He's not running around blocking attacks in melee range. And along those lines, the mace is a fancy, elegant scepter designed to show off Fab's wealth and prestige. It's no thug's club for bashing in heads.
