Messing around on the PTR tonight, Coolidge and I decided to give Ony a try. Entry was free (no necklace needed) since they are planning on lifting the attunement for Onyxia anyway. 45mins later she was down for the count with some nice loot to boot. The quest to hand in her head sadly gave no buff though (at least to L70′s /sigh). Although the 84G we each collected was a nice bonus :)
