I don’t think I’ve seen a more poorly designed loot system in any other game I’ve played. (Swtor, DCUO, Neverwinter and more).
At the moment, I’m 11/12 Normal (and currently progressing to about 70% of the way on Normal N’zoth), 5/12 Heroic. Primarily pugging from LFG with about 4-5 guildies/friends.
So far out of all 16 of my kills, iirc, I’ve received 5 pieces of loot, 1 being an upgrade, 1 being a slight down grade as far as the T3 azerite trait goes, and 2 being pets…
Yes, 2 battle pets.
I don’t understand who in their right mind develops Pets to be gated behind boss kills and (essentially in the first few weeks) progression.
I’ve also been fortunate enough to receive an ‘okayish’ piece through assaults.
On top of this, my heroic drop which was just a direct upgrade from the same item on normal was fortunate enough to be upgrade with… wait for it… tertiary speed stat. 
All on top of just pure misfortune (which I don’t have a problem with, that’s what RNG is.) people in my raid are getting Item level upgrades but overall down grades which removes the ability to trade. For some reason, we removed MasterLoot.
Lastly, people are still getting cloak drops in M+
rant tldr: loot table hasn’t been reviewed at all this patch, let alone expansion. Progression is becoming unfun. Looking for other peoples experiences or opinions/contradictions.
