Please, dont flame me that its common sense, cause from what i see on my server, it obviously isnt.
After 2.4 patch came, people blindly went for daily quest farming and making money only by daily quests.
Result: AH prices of grinded stuff started skyrocketing. All except the stuff you get while doin dailys (primal mana and fire).
Check your auction house for grindable stuff prices, primals, disenchant mats, cobra scales, herbs (although herb prices arent that much affected due to bigger drop rates), mine ores.
You will see atleast some of the prices went almost double up.
At the same time grind spots will be EMPTY, obviously cause all are just doin dailys and not grinding.
That means the gold you grind per hour now will be over DOUBLE than what you grinded before (double price+ empty grind spot)
I dont know the exact situation on other servers, but on the 3 servers i checked primal air, primal water, primal life, primal might selling, mines and cobra scales went up by alot, i made over 400g per hour by grinding primals with no hurry, t5-t6 geared char.
Again, Please, dont flame me that its common sense, cause from what i see on my server, it obviously isnt.
Have fun geting your epic mount within few days if you dont got it already, cheers
