Chances of receiving epic and unique?

It's nice to know this still happens.
I seem to have had much worse luck the past few months compared to last year. I used to usually hit epic in <10 cubes. Now 40 or 50 seems normal.

~40 (almost 4 sets) for my shoulders to hit Epic, then at least 88 (8 sets) used while Epic and did not turn Unique. Stopped cubing since I cannot keep up with these ridiculous NX rates anymore. All broke now </3

I have a friend who spent ~180 Cubes to turn a CZak from Epic to Unique.

We're bad at cubing
