From Eurogamer interview:
Tom Chilton: There certainly are quite a few new profession recipes. We also introduce the epic gems in this patch, and they'll be available only through the normal and heroic difficulty of the Deathwing raids.
I read that to, but I seriously doubt they want gems to cost over 1k.
So basically inflation?and let's face it, there is ALOT more gold in the game now then there was previously... making gold is fairly simple for more players given time. (botting just makes it easier for us cause we are doing the same things that they could do, just for longer periods of time of when we don't have to be sitting there doing it ourselves). More gold = people willing to pay higher prices on goods.
thats also a good news for Rare gems, Price are gonna be High too, why? cuz not everyone are gonna spent 1k gold on Epic gems
Lot of people dont really like to pay 1k gold for +5 agi or +10agi (w/e difference its, at least its +20+)
