I already disable character bonus, but it seems that at low levels completing one quest gives a level each time. I am a subscriber, so i think there is a bonus from that, which i can't turn off. Any clue as to how to make it happen?
You can right click your xp bar and choose to turn off xp, other than that I don't believe so, but at least you can stay at level if you are interested in doing all the quest in one area.
