So for most people (the ones with +10%):
Do the quest line in Dread Waste, hand over 79 fish to Nat Pagle (can be done in 27 days, where you should do 3 dailies 12 of those days, thus
hand in 36 dailies. This should give you maxed reputation with both factions and thereby save you some time to do other dailies.
