Finally rerolled one last night. Maybe around my 40th roll...not including the rare bow crafts.
Oh trust me. I craft with rares as well as re-rolling. I crafted another bunch of rares last night...got 5 Yangs but all non-ancient. RNG is RNG...I will eventually get one.
They need to incorporate trading back into Diablo. I feel like that was a major part of D2 popularity. I personally would go on D3 to do some trading if I was a bit bored of grinding.
I dont think anyone is as bad luck as me. Para 800 now and re-rolled over 30 times and crafted numerous rares and still no ancient yang!. I am about to give up on my DH and move on.
