If you’re looking for an alliance leveling guide there are many available and you can also get some useful add-ons that you can use in game. These can make the leveling process dramatically faster which is great if you have leveled your own characters before and want a bit of a break from the grind.
Getting an alliance leveling guide is possibly not the best idea if it is your first character though. Part of the charm of just getting to know the game is getting lost and not knowing exactly what to do and finding things yourself at a natural pace. However, once you have done all this, you will find the leveling can become a bit of a chore.
If you want to level a character quickly, then you should also consider which class to play. Some classes level significantly quicker than others. It is generally believed for example, that the warrior is the slowest class to level since they have no speed enhancements and to take quite a while to kill things.
You should also bear in mind that certain classes are faster to level than others. It is generally considered that the hunter is the fastest class to level since they can have effective combat pets which make them like a team of two.
At a later levels, mages are also extremely effective leveling classes, since they can start using their area of affect spells to take down multiple enemies at once.
Although it is a complex class to learn, the druid is also a good choice if you want to level quickly. This is because druids can heal themselves. Shamans can also do this so they can make another good choice for leveling speedily. It largely depends on how you play, and indeed rogues can be very fast to level as well since they can sneak past large numbers of enemies to get to their targets. Whichever you pick, an alliance leveling guide will expedite the leveling process.
