Based on the ore reduction that came with 5.1, and threads like Shufflers - Suck up those cheap ores & gems, NOW!, I'd like to ask about your stockpile of shuffling input/output mats, and if you consider buying even more (if at low price):
I still have:
33'000 [Ghost Iron Ore] <-- still buying cross-faction where the ore is at ~30-35g (if available, @80-100g on my side)
1'300 [Roguestone] <-- still buying if < 5g/ea in order to craft perfects that I can sell between 200-300g
1'200 [Tiger Opal] <-- still buying if < 5g/ea in order to craft perfects that I can sell between 200-300g
1'500[Alexandrite] <-- still buying if < 5g/ea in order to craft perfects that I can sell between 200-300g
2'100 [Sunstone] <-- available at < 3g/ea, but not sure if I should buy them...
2'100 [Lapis Lazuli] <-- available at < 3g/ea, but not sure if I should buy them...
2'100 [Pandarian Garnet] <-- available at < 3g/ea, but not sure if I should buy them...
420 [Imperial Amethyst]
380 [Vermilion Onyx]
430 [Wild Jade]
550 [Sun's Radiance]
590 [River's Heart]
500 [Primordial Ruby]
1'700 [Serpent's Eye] <-- will definitely not BUY those ^^
1'500 [Spirit Dust]
250 [Mysterious Essence] <-- still have like 200 rings/necklaces do be disenchanted
- I'm making a huge amount of gold buy selling cut gems (primal diamonds included), since many others are suffering from the lack of ore that has been on our faction for like 2-3 weeks now
- Enchanting mats are moving quite slowly... the same applies for enchanting scrolls
