Sleepers Tomb has been retuned, on legends at least. The last patch included the sleepers.chr file, which updates the models available in the zone. Apparantly the patch retunes the Pre-Awakening content, as well as adds a completely new dataset for post-Awakening content. I'm told this should be going to live servers in 4 to 6 weeks.
Found that info here:
