Sooo ready for Cataclysm ?
I threw a few quick notes on how to get ready for my guild, repeating it here, hope it helps!
Professions- 450 to 525
- Alchemy : transmutes + flasks = lichbloom, frost lotus, goldclover, eternal life. Gather stormvine and cinderbloom, fish albino cave fish (deepholme) as soon as you can
- Archeology: --- Do not solve anything until you reach 100. Will clog your backpack and later you will need the parts to do cool stuff
- Blacksmith: titanium should get you up to be able to do folded obsidium . You will need LOTS of obsidium bars. Eternium only starts to level you at 480
- cooking: Fish Feast, nettlefish, glacial salmon, musselback, later buy a recipe for broiled mountain trout, is the easiest to fish, at hyjal
- Enchanting: cosmic essence, abyss crystal, dream shard (greater stamina on bracer), de all the greens and blues you get questing to level more
- Engineering: titanium bar, eternals (water, air, shadow, fire, monarch topaz, heavy borean leather), later you will need tons of obsidium bars
- First Aid: -- just use the embersilk you get questing
- Fishing: -- fish "mountain trout" at hyjal, albino cavefish at deepholme (to level alchemy and cooking)
- Flying: -- pay 200 for Azeroth flying, 5,000 for speed flying (310%)
- Herbalism: -- Cinderbloom and Stormvine at hyjal. Cinderbloom is best for leveling, stormvine sells better.
- Inscription: runescroll of fortitude (snowfall ink) to level past 450, later blackfallow ink, ashen pigment from cata herbs
- JC: you are going to need tons of nightstone and hessonite. Get it mining or prospecting obsidium ore. Oh and you are going to need obsidium bars also
- Leatherworking: heavy leather jormungar scale, icy dragon scale to do drums and level past 450, later farm savage leather
- mining: mine obsidium!!!!! Only available in good quantities on hyjal. Eternium is very easy to find, pyrite easy also
- riding: -- n/a
- skinning: skin savage leather, savage leather scraps from any cata beast, for leveling lw
- Tailoring: spellweave or similar to get past 450, later do bolt of embersilk with the embersilk that drops while questing.
tl;dr Bottom line: Mine obsidium!! It is needed to level jc, eng and blacksmitting. Will reach good prices on AH.
Instances or Quests for leveling 85 ?
- I hate questing, so I would pick instances... Except that you will need a lot of reputation to get good gear, good head and shoulder enchants and good recipes. And the only way to get them before you are ilevel 328 (minimum for queing for hc) is questing.
- Questing also gives you rep with guild, which will help you and the guild. A lot of guild achievements only count if the member is friendly with guild, a lot more only count if the member is 85 and honored with guild. Guild achievements give guild goodies

- There is also the fact that a lot of people will be learning the instances, i.e. pugs will be brutally frustrating.
- So personally, I'd strongly recommend questing for leveling. You get to see the new areas, get rep and don't wipe (quests are easy as pie!).
tl;dr Questing will give you rep for good Epic gear. And is faster.
Why you MUST grind Tol Barad rep ASAP
- Tol Barad gives Hellscream's reach rep on Horde side, but the same applies to ally side
- Hellscream rep is the quickest way to epic level gear you can get. 2 awesome level 359 trinkets and a level 359 weapon. plus tons of honor for the pvp stuff you will use till your pve gear is up to date.
- Oh and you get 2 mounts too

tl;dr Tol Barad is the new WG and you should do it every 2 hours and do dailies. You will be very glad you did.
