It’s just RNG. I got 3 uniques yesterday, and have gotten between 1 and 4 legendaries in every mystery box.

RNGesus

I’ve still been getting uniques at a similar rate so I think you’re just having bad luck. That being said I’ve only been doing higher tier nightmare dungeons. From what I remember they buffed helltides drop rates from some enemies I think

I'm inclined to say bad luck... My luck is non-existent in this game and has been since early access. Leggos rarely drop, often 1-2 from mystery chests, none from goblins and a handful from whispers.

About 75% of my total playtime has been alongside my partner who gets leggos at a comical rate. He got 4 uniques in 2 hours the other day, and I've had 4 total since we hit WT3.

Blizz just hates us I guess!

I speculated the same thing but for nightmare dungeons. I seem to be getting significantly less loot, but that could just be the RNG of it all.

Blizzard has already nerfed quite a bit in an attempt to stretch out the end game and nerfing drop rates seems like an obvious step in that.

Got 6 Legendaries in every chest today atleast. So did my friend i played with :)
