I’m at 7/8 and cannot complete “Birth of a Warchief”.
I’ve got absolutely NO help from all the many online WoW “databases” and I am still convinced that Blizzard has over-complicated what used to be a fun way to pass the time.
Playing my Paladin “Pelf”.
Look on wowhead for the quest There is no hope, that should be the final quest in that series, I think. If you look it will have every quest you need to get to that point, my advice would be to start working your way back, it might have sent you out to a different zone at some point, but either way, that should help you figure out where you are stuck.
