Below are a few changes implemented in 1.9.3 that unfortunately, did not make the patch notes.
Nefarian's reset should now consistently be 15 minutes regardless of what phase your raid may have wiped out on.
The High Priests, High Priestesses, and Jin'do the Hexxer will now drop their epic items more often. Some of the rarest items from Zul'Gurub such as the Warblade of the Hakkari and Zulian Swift Tiger can now also be found a bit more frequently.
Zul'Gurub coin and bijou drops were increased
The stats on the Tier 1 Mage and Warlock sets (Arcanist and Felheart) have been changed.
You now have to be out of combat to open a chest.
Uno de my guild dice que son ciertas, ayer hicieron ZG y estaban comentando que ahora recibian mas bijous.
