I don't know why there isn't a piece of jewelry that I could farm for that has grant Mojo Rising upon it when all its counterpart talents such as grant first strike, grant relentless, and grant burst fire are all on one piece of jewelry that can be farmed. This puts witchdoctors at even more of a disadvantage in PvP as it essentially makes it so much more difficult for them to properly gear up for chains. Mojo rising can only be learned by witchdoctors and they can only learn it to one, pets can however have it on them and I think some weapons might, but the fact still remains that of all those talents every one of them can be had on a piece of jewelry as a grant except for the witch's Mojo Rising.
