If you want to learn how to get to level 80 fast then this article will help you out. There are lots of different opinions on the quickest way to reach the level cap and some people say grinding is the best way while others think it is questing.
I would say having been through the game a few times that the quickest way is questing. The thing that you must make sure you do is group all your quests together and then you will find that you shoot through the levels fast. A lot of people think questing is slow because they do not group their quests together and what I mean by this is making sure that when you are in a certain area to pick up every quest there.
Then all you have to do is go and do the quests and hand them all in at once and you will get loads of XP.
Another good thing about questing is the fact that you always receive the same amount of XP even if you are not in resting time so you don't need to worry about that either.
Of course if you add grinding to this killing beasts and mobs on the way to your different objectives it will not hurt, and will make leveling faster!
You should also have a look through some popular add ons that you can install like LightHeaded and Questhelper to see you through the game quicker.
Lastly make sure that you try and log out in an inn every time, as you will get double resting time and this can really help when you want to level fast!
I hope this article has given you a few pointers on how to level fast in WoW and the above advice will improve your leveling speeds I am sure!
