There is a constant market for transmutations. If you are capable of doing these, you can charge an upcharge on each of those transmutes. A player who logs on his/her character each day, and sticks to it, can generate a significant subsidiary revenue scheme through transmutes. Likewise, if you have a transmute that allows you to transmute a lower value element (such as Earth) into a high-priced one (like Water or Fire), you can make a cool 15-20 profit every day by simply doing your transmutes.
Nov 10 well i tryed i was hoping to comeback to wow after being away since cat but my only real interest was pvp. seeing the state its in now i can see it's not worth bothering with and i feel i've given it enough time. the only choices i see for pvp is to twink so i can beat on kittens (cause i'm so 1337) or be so under powered i'm useless as i watch the twinks decimate my team. i didn't return for the american gladiator experience. it's a shame i missed legion i feel i would have like it better.Piale5	Nov 10

Whatever your approach, if you use some common sense and apply yourself, you can make significant quantities of money in the game. By managing your cashflow, conserving and budgeting where you can, and investing wisely in those activities that make you money, you can become financially solvent relatively early in your career, and remain comfortably well-off (while still buying good gear) at level 80. Good luck!
As always, I will monitor and update this guide as new information comes in. If I've gotten anything glaringly and completely wrong, just tell me with as much data as possible. The idea is to find the fastest possible leveling method, NOT to argue about how good or bad individuals are. If you have hard data, post it! If you have an idea, let the thread know so we can test it!
First of all, the value of transmog is decided by rarity and how they look. Some items like Minenarbeithut der Tiefen or Pendel der Verdammnis (they can drop in Uldaman) are worth millions of gold. They are worth so much, because they have a really small chance to drop. Other items are bought well because they look good. Best example in this case is the Glorious set, its legplates Glorreichen Beinplatte reach a 100.000 Gold value easily.
