I have obtained a few gold making guides off this site (ty for the posts) but the authors must think we are thick. There is nothing in these guides that a quick look at the AH and then thottbot couldn't tell you, and nearly all of them recommend hours of farming for $wow gold$. Nearly none of them promote proffs, and if they do it's all the Pre-BC mats that NOBODY BUYS any more, so here is how I am starting to make gold
<<You will need a chanter/tailor and later on a miner/blacksmith>>
First off, start with a tailor, and pump out as many Netherweave braces as you can!
at only 18 netherweave cloth and 1 rune thread they are cheap to make. Then comes the really smart part... DE them. The drop chance on lesser plannar essences is fairly good, and the odd bit of arcane dust and shards always helps. Farm enough so you can create at least 10 greater plannar essences, then sell them for about 145g for 10, you should make more from 1 of those than the netherweave and thread cost. If you can farm your own netherweave, so much the better
The same can be done with netherweave pants, but tese are terribly risky, when I did a load and DE'd them I lost a lot of money, but these are farm more rewarding if it does pay off!
Now, for the BBIIGG BBUUCCKKSS. You will need a high level BS for this. On this BSing character, buy out stacks of adamant bars/ores, whatever is cheaper (2 ores = 1 bar remember). Do not buy anything if 20 bars is gonna cost you 75g-ish or more! Now, we trun our adamant bars into ADAMANTITE CLEAVERS! At 8 bars a wep these are cheap to make. We then send it to our chanter character and DE the weps, you can expect drops of 1 to 2 GREATER PLANARS a DE, sometimes 3. The off chance of a large prismatic shard dropping is also an intensive. You can be a bit unlucky and sometimes get some arcane dust, this is rare however, the essence have a higher drop chance
Hope this helps, any questions pst me on Torquez (70 pally) or Torquae (63 lock) on my server (use wow armory to find me)
... oh and plz +Rep me :-P... cos I need it
