As soon as you start the game with the guide installed, you will see the interface. Normally you can adjust this to suit your own needs. You can make the steps show you a lot more information, this takes up more screen space, or simple instructions which take less space on your screen.
Put the directional arrow somewhere where you can see it without having to look for it on your screen with your eyes. A good place for it to be is in the center of your screen, right above the quickbars. That way you will always see it and won't have to stop to see where it points you.
As you reach a quest objective, pay attention to the directions on your guide interface. They will update once you need to start killing NPCs or when you need to pick up something. In order for it to be more effective, set the guide to show you a few steps in advance. That way you will be able to organize yourself better.
If the guide stops working, or you notice a glitch, disabling and re-enabling usually fixes it. Once you got used to the interface, it should be real easy to level up your character. If the WoW Alliance leveling guide you have doesn't have the things you saw mentioned here, then you don't need it. You should only use WoW guides that can be used in-game. It is faster.
Using a 1-85 Alliance leveling guide is a very nice way to make sure that you will level up fast. However, most guides cover every area in the game without saying which ones are best. This can be problematic for players who don't have a lot of experience with World of Warcraft. Mostly because they can go with the areas that have time-consuming quests that don't give good rewards.
To help fix that problem, I will share with you some of the best alternatives when it comes to leveling areas. For starters, as an Alliance player, you should use Eastern Kingdoms to level from 1 to level 60. This continent has a lot more Alliance territory and better areas to use. The majority of them have flat landscapes which are better to use with normal mounts.
The next area you will go in will be Outland, where you will level from 60 to 70. The zones you should choose here are Hellfire Peninsula, Zangarmarsh, Terokkar, Nagrand, Blade's Edge Mountains and Netherstorm. An alternative for Netherstorm is Shadowmoon Valley, but this zone is not as good as the first one. So if you use a 1-85 Alliance leveling guide make sure you go with Netherstorm.
For the 70 to 80 area, you will be going to Northrend. You have several options to choose from here, but I suggest you do the following: Borean Tundra, Dragonblight, Grizzly Hills, Zul'Drak, Sholazar Basin and Icecrown. You will notice that the first and last areas have other alternatives. cataclysm leveling guide, Leveling Up With An Alliance Leveling Guide, Alliance Leveling - Cataclysm Leveling Tips For Alliance
It gives them a sense of freedom as well as letting them fight for the side that they believe in instead of the classic one way game. This allows people to work with others and go against the opposition when they want to.
