As many of you know, I like to try to level as quick as possible. This life, for my heroic levels, I decided to log everything to see exactly where it ended up.
Not my quickest but still pretty good. The times listed is the end times as shown on the "x" screen when a quest completes and doesn't include any travel time. If I entered late, I would manually track the time I was in the quest. The XP per quest was calculated based on the total xp accumulated after the quest, minus the beginning. It would include any incidental xp such as monster manual awards.
