Some tips:

- Might is useful but focus on Agility without forgetting about Will and Fate. keep agility over the others and Might over Fate. Might and Agility will help with parry and critical hits.
- Use will and In-Combat Power Regen (ICPR) if you notice power is running fast.
- Do not trust blue items from jewelers, lots of people is rushing for this (and raising the price at the AH). You can get better items from Angmar quests that will be more Hunter focused even though they are purple items.
- Use traps and focus as much as you can. Use crafted traps, chants and fear (Bards arrow, Cry of the predator) to deal with multiple mobs.
- Use Rain of Thorns to deal with multiple mobs too. Notice the spider icon to see who is trapped and focus on other mobs first.
- Use food and athelas potions to keep you alive.
- Use quick shot to slower enemies.
- Get used to maintain focus so you can use Merciful Shot to finish a mob. This saves time, power and health.
