So, I made a mistake by clicking delete on the beginning quest *(2 minute timer)* and it gives only 100XP per completion but once the quest is complete and you choose to finish you get the experience. Delete the quest and pick it right back up, it's essentially 6000 XP per hour on your champion if you would like to take it that far but you're able to get unlimited experience on your champion of choice in the beginning of your class hall, essentially an exploit - thought I'd share. Quest name -> "A More Wretched Hive of Scum and Villiany" - I would almost say it potentially works for ALL mission quests in your Order hall upon completion deleting and doing again.
