I think there is some truth to that.
I played probably 7-8hrs my last session.
Moment I log in, first group of mobs I kill, I get a unique.
And yeh it's not a good unique but it's not the point I'm trying to make. It's the fact I got one instantly on first drop seems a little sus to be pure coincidence.
Also I'm sure the game tracks what you save your chest, what you shatter, modify and especially what you equip...cuz the moment I started stocking up on critical strike avoidance shards right after I equipped my first exalted with 57% CSA on it, I kept getting more a CSA and armour with CSA %
