All new games require adjustments and improvement. A simple fix while you do that would be to turn the crafting drops back on (let them flow) and lower crafting costs.
Let players craft and experiment, you’re killing your own game by making it rare to uncommon. Why are you restricting access to one of the few positives of the game?!?!?
It was crazy fun at first now it’s freaking work!
Class alignment, issues, and complaints are going to be here no matter what you do. You can’t please everyone but you could very easily bury much of the negativity in more loot drops and massive crafting/experimentation. The current drop rate is going to kill this game.
