There have been a lot of posts around the blog world after each PTR build, but some of those have been weeks (or months) ago, and it becomes pretty easy to lose track of the changes that should pique your interest. What follows are the top three things I think are important to keep in mind in the days before the patch.
- New BoE patterns. Three new JC metagem random world drop recipes, all of which are going to be unbelievably hot commodities for the rest of Cataclysm - Wowhead is showing that they are +54 Agility/Strength/Intellect with the +3% crit damage, making them strictly better than the Chaotic meta, in every possible way. So stop making Chaotic cuts immediately, and you may want to consider dumping your remaining stock as well. It may be a while before the new metas saturate the market, but you don't want to be left holding bag either.
Enchanters are getting three new +50 Agility/Strength/Intellect wrist enchanting patterns, which are also BoE world drops. The demand for the patterns themselves will probably be high, but since all three require two Maelstrom Crystals to enchant, I would not expect high demand until after 4.1 (when I expect the new 5m to drop epics on heroic).
- Expect a surge in herb/Volatile Life prices. The number of herbs needed to make flasks will be reduced by approximately 33% across the board (8 of two kinds instead of 12). This reduction in mats should correspond in a surge of demand because now A) making flasks is closer to being profitable, but more importantly B) getting the guild achievement Mix Master is now within (easier) reach. To get some idea of the scope of the change, the herb reduction means a guild will go through 400 less stacks of herbs. Yes... four-hundred stacks. These aren't 400 stacks of Cinderbloom either (for the most part). The Volatile Life demand will come as a consequence of the quantity of flasks being made, especially since each flask will take two more Volatile Life each, basically creating an extra 2,000 Life demand per guild.
Also supporting the extra herb/life demand will be the new Alchemy trinkets, like the Vibrant Alchemist Stone, which are amazing. Whether the alchemist never made one before or if they made the +Stamina version, chances are good that every Alchemist on your server is going to spending 50 more Volatile Life and nearly two more stacks of herbs each.
- More people will be running heroics. Not only have almost all the heroics been targeted with some precision nerfs, the recently announced broad-spectrum, ICC-esque 10% buff to players using the LFD tool will mean more successful heroic runs are being made. More successes mean it's more likely that individuals will queue again, which means more cloth, more enchanting materials, and ultimately more demand for enhancements like gems, flasks, and even enchants as players more quickly replace their old gear and perhaps move on into raiding.
The second is that Love is in the Air holiday is also starting on Sunday. It remains to be seen whether or not there will be any explicit money-making schemes like there was last year (Lovely Charm Bracelet fiasco anyone?), but it has been "confirmed" on Wowhead that the holiday boss drops ilevel 346 necklaces this year, some of which are strict sidegrades to the crafted JC ones. So if you were prepared to put down the cash for one, you might want to slow down. And if you were planning of selling some, well, you still might, but I would not take any undue risks attempting to do so.
