Hello,
There are only two weeks left until the new patch will hit the servers and from my knowledge from there on it will take another ~20 days until the new recipes can be bought. Enough time for some last minute investments!
Since I couldn't find a thread with a specific list on what to buy I figured I could tell you my list of goods to stockpile.
As you may know, there will be many new recipes for
Leatherworking,
Blacksmithing and
Tailoring. If you have characters with this professions, you should do the upcoming dailys every day. The recipes will available after quite a buch of dailys so you shouldn't miss out on that.
Also Jewelcrafter will get new recipes but they won't have to do dailys they just need to learn them.
You can either just buy the raw materials as cheap as possible and sell them for high profits or you craft the new items and sell them for even higher profit. I will give you my list of goods which includes almost everything that the recipes need. Raid your AH!
Volatile Earth
Volatile Water
Volatile Fire
Volatile Air
Elementium Ore
or
Hardened Elementium Bar
Inferno Ruby These willl
skyrocket!
You can also buy a few from all the other gems as they will be needed as well but not as much as the
Inferno Ruby since it is not only needed for crafting but also a lot of players will get new gear and therefor need to fill their sockets
Pristine Hide
and/or
Heavy Savage Leather which can be converted into the hides.
EVERY tank will need at least one of the new leg enchant and therefor needs one
Pristine Hide, so there is a lot of potential here since its also needed for every one of the Leatherworking recipes.
Last, but not least:
Truegold
There are SO many promising Blacksmith items that will need it! This will be
HUGE!
So, now that you have a list of the materials but you should not just run straight into your AH and buy everything. Watch the prices for a few days so that you get a feeling of what is expensive and what cheap. Then set yourself a maximum price for the selected good and buy everything below it. You have still a few weeks to get a nice, big heap of cheap goods so be patient!
If you want to invest even more, you can start to buy cheap enchanting materials. Every raider will get a lot of new items and needs either the enchanting scrolls or the raw materials. Same goes for flasks and the materials for fish feasts as more people will go raiding again and eventually wipe
Here is a nice list that shows the recipes for each profession if you just want to buy for a certain one.
I hope this helps and I apologize if my english is sounds weird sometimes. If you have any additional questions, feel free to ask!
