The first few Faires that happen after the launch of an expansion are always busy, mostly because of the trinkets you get for turning in the decks made with inscription (either cards made once a day or whenever you can).
However, this is the first Faire where you can get the full advantage of the revamp and work on the monthly quests they give you.
It's +5 skill points per tradeskill and the tasks they have you do are incredibly easy.
And it's not something to laugh at when you could use the new MoP mats to some better use.
If you're not maxed out with your primary or secondary tradeskills, it's definitely worth making a little side trip with all of your toons.
PS: You'll probably forget it, but don't forget to bring 5x Simple Flour before you go (or grab a bunch to sell to people on-site).
Tradeskill help from the Blingtron 4000
Some Engineers have already crafted the handy Blingtron 4000 already.
Inquisitive minds will have noticed in the tooltip that he gives a random present to people each day (to level +80 characters only).
What is mighty interesting about that is that the present has a chance to give a Fire Spirit, which gives +3 skill points to both of your primary professions (if they're not already maxed).
So if you're in your main city and you see a blue daily quest icon appear on your minimap, chances are someone dropped a Blingtron (he stays up for 10 mins).
It's an 8% drop rate, so don't feel too bad if you don't get it - someone will be looting a Party G.R.E.N.A.D.E., and you'll be dancing your worries away!
It looks like some Cataclysm markets, after sinking completely, have been left wide open.
Gold-makers should take the advantage of resetting those markets, being very careful that a lot of people that log late in the game will try to (unknowingly) crash the market all over again.
It that happens, it will take a lot of effort to make a stand and keep the prices from falling too low, but there's a way to claim a foothold on these few markets.
And it's certainly important to do it, as the spotlight is shining brightly on crafting leveling right now.
(Note that the enchanting market of Cataclysm will probably take a few more weeks before we can delve into it seriously a.k.a. make ridiculous profits out of it.)
Guild Standards - the buffs that everyone forgot
No, it's not a way to make gold - it's a way to get rep and XP faster.
The guild vendor can sell you 3 standards that give out respectively 5%, 10% and 15% buff on rep and XP gains while killing monsters.
So you might want to look into this when you're farming mobs, running dungeons, etc.
Personally, my standards are almost constantly down all of the time.
Take note that they have a big cooldown on each one of them, so you should try to maximize their use as much as possible: put them down in the middle of your killing spot or room.
The range of the buff is remarkably big and no, the buffs don't stack from multiple standards.
Here's a very detailed explanation of what works and doesn't work, if you're so inclined to know.
I know that a lot of people are turning to gold-makers to know what sells and what doesn't.
I know that they want to know that if you sell Item X for Price Z it will equal W Gold (where W is TONS of goooooooooooold).
But the truth is that gold-makers can only get a feel of what the worth of items could be like.
What it comes down to is what's happening on your server, and the beginning of an expansion is the best time to try some experiments on the Auction House.
You'll never know what you'll end up catching!
And maybe, in the end, you'll have discovered your own little niche market.
Who knows ? You'll know.
Have a little fun. :)
