Hey,
If you haven't collected all the Dreanor treasures, you might still be able to pickup this item : Obsidian Frostwolf Petroglyph - Item - World of Warcraft
Another equivalent item is available in Shadowmoon valley : Ashes of A'kumbo - Item - World of Warcraft
What it does is giving 5% rested XP on use, which can be used to speed up slightly your progression when Legion hits.
There is also treasures from Spire of Arak that are meant to not work above level 99 but actually do work on the Beta thanks to a testing from Scrud :
Hope it helps some of you, you'll save maybe 10 minutes of leveling, but it takes 30 seconds to get so why not![]()
