Bmah and T3 help?

I’m looking for warrior t3 shoulders and I’ve checked every day since SL came out and I’ve seen every other t3 shoulder multiple times and this one zero.

Is there anyone with a lot of bmah experience that knows if there’s average time frames, different chances for different pieces or anything like that?

I can’t find much info at all about bmah on the Internet and I’ve been pretty obsessed with finishing my set. Just getting really bummed everyday I wake up and see another shaman t3 piece :weary:
