So long story short, I have 8 Restraints, and still no Focus. The other three players in my group have Focus, and they're ready to drop me for someone else so they can push past the GR40s. I spent all day today running T6 rifts for blood shards/death's breath. I can run T8, but I was able to knock out a T6 rift in a few minutes, so I figured it was better overall.

I've used every DB I have throwing rings into the cube, as well as spending all my blood shards on the things, and no Focus yet. Should I keep doing it the way I am? I really need to get my Calamity and Recurve weapons as well, which I'm definitely going to try cubing for. Wondering if it's a better use of materials to just give up on Focus from the cube, since I figure there's a TON of rings you can get, the odds can't be very good.
