While leveling in Guild Wars 2 it is important that you go about it in the correct way to make any real progress. In many games, players end up grinding the same enemies over and over again, and that just isn’t going to work in this game if you want to level efficiently.
Monsters only give a very small amount of experience when you kill them so there has to be some other reason that you are killing them if you are going to bother taking the time. There are several different reasons to kill an enemy. You could be killing to earn an achievement, killing to finish a reputation quest, or killing to complete your personal story quest line or a dynamic event.
If you run into a monster that you have never seen before in the game, it is important that you kill at least ten of them. You will gain an achievement for taking out ten of those enemies, and you will get a nice experience boost for earning that achievement. You also need to consider if you have killed that enemy at all today because you can earn an achievement for the number of different enemies that you kill during the day and that grants you experience as well.
Personal Story Quest
The Personal Story quest line is very important for your character and is a great way to level up. When you enter into new areas you will see green dots on your map with level ranges. These are spots for your personal story and you should avoid these quests until you at least make it into the level range and it is best to be a few levels above the recommended level. When you reach the range you simply walk to the dot and talk to the person giving the quest. Complete the quest and you will be granted experience and will get to see some nice cut-scenes that bring the game to life.
