Yeah, that's a huge change in drop rates compared to Early Access / beta, considering that I was loading up my stash with tons of uniques and legendaries at much lower levels.
It also gets me that bosses aren't dropping, or at least haven't dropped any, good loot at all. Just regular rares.
Almost every single item that I'm actually using came from a quest reward, or as an item that I purchased in the store in town. Most legendaries were also from quest rewards -- almost nothing has just randomly dropped with unique and / or legendary status.
I'm at about 41 right now and I did have another legendary drop, but it was from a chest, and didn't appear "random" to me.
But, if you're 60 and 6 and 3, then it seems that it's not just my RNG that's bad, considering that I specifically always have bad RNG in every single game that I play. ;-)
