Invest - If you do not plan to rush to level 60 and want to take your time instead, this tip might come in very handy for you. The value of many Items will increase over time because more and more Gold will find its way to the market. To take advantage of this, you can stack up on various crafting materials with the intention of selling them on a later date. This will require a lot of patience and some Grinding if you want to make a good profit but is certainly worth your while if you are an economy-oriented Player. 

Upgrade your bags as quickly as possible - This tip is closely connected to the previous one. Upgrading your bags quickly will ensure that you spend more time grinding and less time managing your inventory, which will increase your leveling speed and allow you to make some more money in the process. Bags are expensive, so it is a good idea to look for a Tailor who will make you a set of new bags for Materials and a small fee (you will surely loot some Cloths, so this will not cost you too much). There are also some Quests that reward you with Bags:
Through out the game, the quest log will be capped to 20 many times.  The guide makes use of maximizing the total amount of quests you can accept at once.  Because of this it is important to follow the guide exactly and only accept quests if the guide tells you to so you won't run into issues not being able to accept a quest.  If you do accept a quest that is not listed in the guide, write it down because you may need to abandon it in order to keep following the guide if your quest log is full.
To gain gold in World of Warcraft, you will primarily be grinding professions which are fantastic for receiving rewards. Mining is an example of a great profession at an early-game level. While Herbalism is actually the best gathering profession, the issue is it uses consumables which can make the profession rather costly, with the investment required.
The name reservation is fair too, i would be pissed if some kid messes with trial accounts or dad buys 1 month sub cause he was good boy and creates 3 characters with random names and never plays with them above level 10. There is some chance one of these random names will be yours. Now, there will be s*itload of people playing and messing with classic in starting zone, first 2 weeks till they get bored or its nothing they have imagined. I guess its only fair, people who will commit to classic have a fair chance to take their iconic names, and jump into azeroth with all their nostalgia and memories, or jump in adventure ahead of them.
