The part I've noticed is that you'll generally get your first two BPs within only a few runs, and then need to farm for ages to get the final piece, when that last piece drops is a little different though. I got my last Ember piece after 40 runs, my last Rhino piece in around 15-20 runs, and got lucky with Saryn's last piece with only 8 runs.

So, mostly luck, but the first two, then a lull, is the usual thing as far as I can tell.
