Stat Guide
For stat points only add strength for your weapon requirements. Don't add any points into spirit. As for dexterity and heal it is your choice. Some builds are 4 dex 1 heal and others go 3 dex and 2 heal. Where to put them is up to you.

Skill Guide
The following skills are skills to get/max:
Critical Fire - Max it. It gives you 5% more critical chance when maxed.
Bow Mastery - Max it. It gives you a 30% increase in bow damage.
Triangle Shot, Wonder Firing, and Flore Novas - Max it. Great AoEs in PvE and PvP.
Crow Wings - Great Skill in PvP. It gains you distance and does high damage at the same time.
Ice Arrow - Max it. Very important skill in PvP for Bow Hunters. Slows your opponent.
Explosion Arrow - I find that this skill is great in PvE because it does high damage and it fills the gap in AoEs when in AoEing mobs.
Slow Arrow - Not completely sure if this would be great in PvP. It does 7k damage when maxed so putting points into this skill could be a wise investment.
Flore Novas - Great skill in PvE. Flore novas is a big 4 hit aoe and most like will do major damage when maxed or close to being maxed. In PvP it is ok, but a disadvantage is that it is shorter range than your other skills. Probably good skill when your enemy is close to you. It has a 2 second global cooldown though.
Wind Moving - A must have skill in PvP. When maxed it gives you an increase of 54% moving speed.Its the boost in speed that is needed in keeping your distance from your opponent.
Cure Wounds - This skill is optional.It helps in PvE when your pots are on cooldown. I highly recommend this skill.It heals about 50 hp per half second which is about 100 hp per second.This skill helps(for me at least) at the lvl 90 dungeons when a segnale's hyper heal is on cooldown.
Terrace Magic - Another optional skill.I find this skill great in PvE for Bow hunters who do not have a lot of stat points into heal. If you are a pure heal build with your stats at weapon requirement this skill will still help.Terrace Magic is not good in PvP though because it cuts your Pk Shield in half.
