The way Blizzard made these "super" Jewels but the Chars that would benefit can't use them properly.
My Dragondin uses Flickering Flame Helm, Dragon Armor & Shield + HOJ -> Ain't got no slots for any jewels
My ZealSoso uses Passion Sword, Dream Helm & Shield + An Treachery or 160/60 Amor - Ain't got no slots for any jewels
My FuryDruid uses eth "Zod" Ribcracker, COH, Jalal's 15/40 - No slots for any jewels
My FireDruid uses Ravenlore (5/5 fire rbf) - Enigma & Phoenix + HOTO - No slots for more than one Jewel after I've Hel the RBF.
So the builds who who greatly benefit from any of those new jewels, cant really use them cause It would mess up the builds.
(My Cold Soso got the most Sexy of Sexy DF now btw, there the destroy the RBF made sense)
You can only wear one of the jewels per character
Every build in the game is updated, BiS has changed for everyone and new items are now BiS
