I might be extremely dumb, but I don't see the reason for this - people say that you should DE greens from your farm instead of vendoring it - why is that so? Let's say that after 4-5 hours of farming I get a ton of greens from MOP that I can either sell to vendor for around 15g each or DE them and get spirit dust worth 3-4g each item.
I might be getting it all wrong, but last time I checked 15gx50 is more than 4gx50... so why? I obviously know that old items with arcane dust, infinite dusts are having their vendor values lower, and that it's much more profitable to DE them and sell the mats(1-2 dusts for like 10g depending on your realm), but what about mop? Why DE and not just vendor for bigger money?
Ore shuffle, as in buy trillium ores and sell bars, if profitable? Buy bars, cut gems, sell?
