Amen! Here is a post I made a few weeks ago:
I’ve been waiting more than 2 months for Skittering/Nerubian to show up to finish out the Expedition Leader title/achievement. The last one I’ve needed was Vorus’arak’s Carapace [Tell me a Tale]. All roads lead to “You have to wait until Skittering + Nerubian week.”
I guess I have to pray it shows up during pre-patch… Completely crap RNG on behalf of Blizz Dev! Getting any support from Blizz at this point of the expansion is probably non-existent. GM’s will not help, either!
