I personally enjoy randomness on the top end crafting, but they really need to solve the low to mid-end with some determinism. Delve league was a great baseline and instead of capping it at mid-end they nerfed it to the ground.

Trading is a horrible experience. They should allow people to set up shops and automate transfer of goods instead of needing to make a party, go to hideout, trade, go back. I know a lot of people want an auction house, but that tends to lead to other issues, so I think middle ground is a better solution.
