Gold sinks vastly outpaced whatever increase there might have been to drops. The whole system needs to be changed like MW material conversion was (maybe not -99% everywhere, but even -80% wouldn't be too outlandish).
Another problem I've run into is veiled crystals. If you ignore rares for a while because your inventory fills up too damn fast even just picking up legendaries, you'll find yourself completely out of them even though you have 1000's or 10000's of everything else. I guess angelbreath is a real problem too, though fortunately that one is a non-issue for anyone who [ab]uses the helltide glitch.
This is pretty much where I'm at right now too. I finally learned how to level a character correctly by the time I got to rogue (#4 to 100) and so I switched over to NMDs after getting a baseline of ancestral gear from a couple helltides. This way I was getting 925 gear vastly earlier than normal so by the time I hit 100 I had been doing rank 91-100 NMDs for 7-8 levels, had gear that had all the correct stats and tempers but wasn't already obsolete due to ilvl being low, and my last glyph hit 21 around level 98. Downside is it's now extremely difficult to replace anything, even though I'm still missing GAs in several slots. I found an xbow with GA vuln damage and hit the right tempers/MW4 so it's almost impossible to replace with a proper bow instead. Same goes with the rest of the slots. Even when I finally find a good GA or 2GA, the fucking blacksmith bricks it every time or maybe I manage to get past that with the right stats but low rolls and then the enchanter runs me up to 2 or 3 million gold trying to get the last stat I need (just basic shit like armor/crit/lucky hit, I know better than to try to roll for +3 ranks to a skill now).
