I think J J J meant that if you did those quests at lower level, you would've gained more than 1 level. Just so happens at your level, it's not enough for 1 entire level. Custom quests sometimes do give exp, but then for now plenty of them is high end (for example, Thanatos Tower Party Quest gives 10 mil exp, in 10 packages of 1 mil exp each)
