updated the guide with this:
''10) Leveling tip:
Almost all mmos have the area where you get the quests in a major hub,that means that all the quest giving npcs are in the same area,you move to from one area to another when you finished all the quests.
now to make the most out of your gaming time try to get all the quests available for you in the central hub,that way you just need to come back once to turn them in.
so when you arrive to a new area,open the map and check for the green circles in it which means that is an npc with quests,grab all of them and then head out to do them,this will be a real time saver since you can maximise the xp gain by not having to go into town or the central hub to turn in one quest at a time.
this may seem like something that shouldnt be mentioned but i have seen players just grab a couple quests and then head out,failing to notice that alot of times the location of the quests are really close to each other.''
