Well, just for general informing, they are getting rid of the tailoring specs from what I remmeber, so all 6 cloths will be avaliable to all tailors, and proving the new gear is going to be good, you will have mage, priests and warlocks wanting to buy them, and with the week cooldown, there will hopefully be a market.

As for Jewelcrafting, there are fire prisms, as of now, costs 3 of each green quality gem.And there will be a way tom get chimaera eye, the new version of dragon;ls eyes. Getting one per char, per day, I think could be a big money maker, as on my server the WotlK version was going for 300g or so.

As for alchemy, there are the transmutes still to the new gems and somethign called krovolian gold. Not specific on them.

But those combinations seem to be the one that are making the cash.

I for one, over my two teams am hopefully going for
teams one, 5 alchemists and jewelcrafters
team two, 5 alchemists and tailors
