What I did was to solo reg dungeons, picking up everything and DE'ing it. While going for Loremaster of Outland. Quest greens + boss drops + random drops will get you through fairly quickly. If all else fails, buy BC armor or get a tailor/LW/BS to make some for you cheaply.
Tailoring, Blacksmithing, Leatherworking greens with level reqs of 50 to 58 (old world mats obv). My advice? go run LBRS/UBRS a time or two and have a tailor turn all the cloth into Runecloth Headbands.
And @Asmodejjj: no, it's the endgame Vanilla dust. He wants to avoid BC gear like the plague.
Non-outland Greens level itemlevel 56 and up give like 1-2 dust each, but at itemlevel 61-65 (random greens level 56-60) dust gains goes up to 2-5 (2-6 for itemlevel 65(level 60).
The lowest Outland greens are itemlevel 81 and up which will give arcane dust and you want to avoid those.
