Rarity Of Ornate+ Chests In Sinking Sands InstancesFollow

I play a 60th Necromancer, and prefer to solo versus group.
I know the % chance drop for Ornate and Exquisite chest drops is lower for soloers than it is for groups, however, whether solo or duo I see that the rarity for Ornate+ chests from named mobs in Sinking Sands instances seems much lower than it is for other zones I've soloed. I spent a lot of time farming Nek Castle in my 30's / 40's and regularly saw Ornate chests dropping there from the Everling Sisters for instance.

A guildmate tells me that previously, Ornate+ used to drop regularly in The Sanctorium, however I'm yet to see Ornate+ from a Sanctorium boss and have only ever seen 2 Ornates drop in Living Tombs. Can anyone explain when this changed, and the scope of the change? Have all the Desert of Flames zones been affected?

Cheers.

I always thought the whole Desert of Ro expansion was weak on loot. Between a paladin a necro I don't think I ever found any upgrades in that whole expansion. I didn't do any raid content there but I did run about all the instances there are to run.
