I am on my last achievement for the Glory of the Delver. I started this process 14 days ago, and have checked EVERY DAY to finish it. Renilash Beckons story has not appeared once in those 14 days. Why? Why is the rotation flip-flopping between the other two stories and never this one?
Why is it so hard to code a sequential order. 1, 2, 3, rinse/repeat. Why does this have to be random and never appear?
Because the devs luuuurve RNG. They’ll go the extra mile for RNG.
That’s the only “why” that will ever matter.
Same here. I haven’t seen it at all!
Yup I’ve been waiting about 2 weeks as well. Checking it daily. I don’t think I’ve seen the delve ach mount yet. Maybe its time-gated and purposely hasn’t spawned that story yet.
I got it yesterday, when the new patch launched here in Aus, so now I’m the proud owner of the ivory beetle mount! 
Same. Finally. They must have read the post.
