Not sure whether this is the right section to put in, or the scams section (Mod move if desired)
Well basically i've found an easy way to near-guarantee yourself a Primal nether per each heroic run
It's slightly a scam, but sort of not :P
Steps:
Get a heroic Group
During the run keep it on Group Loot (or convince them to put on Group Loot)
At end boss, say something along the lines of "PLEASE GREED THE NETHER I HIT GREED BY ACCIDENT!!!!!"
The group greeds the nether
You actually need it
You excuse yourself as a mis-read misclick, and apologise.
A few people may be pissed off with you, but your story is covered and nobody can give you a bad rep (unless you do it repeatedly to the same person over and over again)
And another slight tip: If you have an alt with average gear and a good class for group balance (healer, decent tank, mage (cc)) then use that, it'll be much more sought after than your arms warrior or elemental shaman
/Expect flame/criticisms for this, but it has worked for me and ontop of the occasional vortex sale, i can make quite a bit of gold on side aswell as gearing my alts up :P
