Making gold is all about finding the balance that works best on your server between all the above methods. When you find that balance, repeat, repeat, repeat, until you get the results you want. Never make any rash decisions without first consulting the economy. If you do not think you can make a for sure profit, then do not do it! Change only when necessary, because your clients become accustomed to certain practices that keep them buying from you even if under cutters offer a slightly lower price. If the customer is always right, then show that to them and you will be much more profitable!
By the way, both the guide window and the waypoint arrow can be moved anywhere on screen.  I usually keep the arrow top center and the guide at the bottom right, but go ahead an put it anywhere it makes sense for you. You can even disappear the guide window anytime you like. No point in having it up while you’re raiding the other side’s towns, right? 😉
Another question I am frequently asked is when should one use trade instead of the auction house. On most servers, the auction house tends to have a lot posted right after peak hours, say 1am server time. Combine this with the fact that a lot of people are just sitting in cities and not really looking to the auction house. This is where trade chat dominates the auction house. Tired players are looking for conversation to take their mind off of sleeping or boredom. If you can sell effectively, trade chat will make a greater profit then the auction house outside of peak hours. A few tips to polish those trading skills might include:
For your tank... I'm assuming you meant which race should you be, not which class, since you seem to want to be a warrior! Well, if you were Horde side I'd recommend Tauren for the health buff. But honestly, I *never* pick a race based on the racial features - only based on the flavor. If you are going Alliance side, I am quite partial to dwarf warriors myself but pick whatever seems most fun to you!
And if you decide you need to go back to an early zone to get low level minerals or herbs? Instead of meekly wandering around ignoring you to gather in peace, now the local mobs are the same as you again and aggro on you. So you have to fight your way in and out. Same spell rotation, over and over and over. 31373433. 31373433. 31373433. 31373433. 31373433. 31373433. Every combat the same. Over and over again. Never ending. No change. Mind numbing. No challenge.
-Gameplay- Gameplay has largely been stripped down to be a shell of its former self. This trimming has been going on for several expansions, but now it's even worse. Classes only have so many buttons which has resulted in very little skill involved in PvE (even PvP is a faceroll for most melee, lacking any sort of depth and decision-making as it's pretty clear what buttons to press in any given situation) and it's become more of a gear check. This expansion gave zero new abilities to classes, only took them away.
Most of the time you spend leveling will involve questing and slaying monsters, but there’s also a lot of travel. Travel earns you little experience (you do gain a bit for discovering new areas), so it’s wise to keep travel to a minimum. The new level scaling system, which scales zones to your level within a preset range, helps with that. You can choose what zones you want to experience and stick with them until you finish their quests.
This is cumulative, as you take into account each failed sale as a loss. In the event too many deposits accumulate, you must decide whether to continue selling the item inflated by too many sales or finding of another way to dispose of it. One final tip: when you find that an item fails to sell in one AH, selling it on the other may finally dispose of it and get you your earnings.
