Power leveling can be a pain sometimes, but by following a few simple guidelines you can make it very easy. First off, I'll discuss the three methods of leveling. Questing, grinding and instancing. Everyone has their own opinion of what is the best way to level. Really, if you want to be leveling in a fast and efficent way, you should mix all three methods together.

Grinding for long periods of time is very boring, so just grind for as long as you can. Try to find a spot where the monsters die fast and have good drops. Now, go out and do as many quests as you can, but try to not always be running back to town. Eventually, you will only have group/elite quests left. This is where you run an instance. Pick an instance close to your level, do all the pre-quest work and then run the instance until its starts to get a bit boring.Then is time to grind.

You may be able to solo some, otherwise just find a group to help you. Now your level is probably high enough to move on to the next zone and repeat the process. After all of this, your ready to do the elite/group quests. Using a mixture of power leveling techniques allows you to obtain the benefits of each technique without becoming bored quickly. There are a few other things that could speed up your power leveling. But I think the most quick way is to go to buy power leveling service online. Upowerleveling can be your best choice.
