Heavensward Leveling... aka Northern Thanalan Leveling

[Furiea]

Personally, I've taken to doing Daily Hunts for exp. Each Tier 1 hunt set (1-3 mobs) gives equal exp to an NThan FATE with armoury bonus (around 21k exp), Tier 3s give 24-48k depending on the hunt. You can do these as many times a day as you want. Complete a set, go back and restock.

Daily Duty roulette main scenario gives 18% ~ 23% level exp
Daily Hunts gives 20k+ exp and you get about 10+ to hunt on a daily basis.
HW Dungeon gives 18% ~ 23%

It is sad to see people going back to North T. and not embracing any new content for EXP.
At this point.. it is probably easier to scale down the EXP received from N.T. Fate drastically after lvl 51 rather than bumping everything else up.

Sorry, edit on the daily hunts. Apparently you can pick up one set a day, but if you don't complete the previous day's set, you can complete that one and pick up another one.

Otherwise, it appears they're once a day, still really good exp though.
