Hunter

All skill evaluation for hunter were given by 3nforcer and Splurd. So, the credits goes to them.

Bow Specialization
Mastery Level: 10
Skill Points: 20

Required Level: 21
Required Weapon: Bow
Prerequisites: None
Type: Passive
Description: Passively increases damage by 1% per level (10% at max)
Max it since it is a passive damage buffer and most importantly cause it is a % increase.
In summary, max it since it is a passive damage buff and is a % increase.

Falcon Frenzy
Mastery Level: 5
Skill Points: 20

Required Level: 25
Prerequisites: None
Type: Active (Cooldown: 10 sec) (50 MP per use)
Description: Summon a phoenix to hit up to 5 targeted enemies in front of you. Phoenix does 5 attack to each enemy. 140 attack at level 5.
Falcon frenzy launches up to 5 targets, both ground and KD, after hitting them for 5 times. Miss rate is high for falcon frenzy.
In summary, get falcon frenzy to level 3 to unlock wolf rush

Wolf Rush
Mastery Level: 10
Skill Points: 30

Required Level: 27
Prerequisites: Falcon Frenzy level 3
Type: Active (Cooldown: 10 sec) (50 MP per use)
Description: Artic wolf hits up to 5 KD and ground targets and causes KD effect.

Targets struck by wolf rush will be stunned for 0.5 to 1 sec before getting knockdown (not sure if you can continue shooting them during this stun effect).
In summary, a great AOE skill for hunter.

Acid Arrow
Mastery Level: 5
Skill Points: 25

Required Level: 23
Required Weapon: Unkown
Prerequisites: Random Shot lvl 1, Bleed lvl 2
Type: Active (Cooldown: 3 sec) (20 MP per use)
Description: Deals moderate AOE poison DOT dmg to enemies in front of you (up to 5 targets). On-strike and DOT effect increases per level.

Acid arrow causes mini stun effect; 0.5 sec. Splurd comment that acid arrow damage isn't that great in PvP as rising shot > air combo works much better.
In summary, not a very good damaging skill, but the ministun effect is good to have.

Sharpshooting
Mastery Level: 5
Skill Points: 30

Required Level: 23
Required Weapon: Unkown
Prerequisites: Acid Arrow level 1
Type: Active (Cooldown: 2 sec) (30 MP per use)
Description: Stun a single target. Dmg increases per level.
According to 3nforcer and Splurd testing, sharpshooting deals high damge in PvP and very low damage against mobs (most likely a bug). Sharpshooting requires a disabling skill to combo with (probably non bugged netbind?) due to it's long casting time (about 2 secs).
In summary, a great damaging skill in PvP. Damage seems bugged in PvE.

Splash Trap
Mastery Level: 5
Skill Points: 25

Required Level: 23
Required Weapon: Unkown
Prerequisites: Falcon Frenzy level 1, Sharpshooting level 1
Type: Active (Cooldown: 5 sec) (20 MP per use)
Description: Create a trap. Explode when enemy step on it. Trap disappears 10 second after cast or when activated by enemy. Dmg increases per level.

Splash trap damage was bugged in Alpha II.
In summary, bugged skill so we can't tell.

Hallucination
Mastery Level: 10
Skill Points: 30
Required Level: 25
Required Weapon: None
Prerequisites: Decoy level 1
Type: Active Buff (Cooldown: 60 sec) (50 MP per use)
Description: Raises evasion rating.
When i used a lvl 3 blur in alpha, I don’t see much of a difference in the dodge rate. Might get it to level 10 in close beta to test it again.
In summary, need more testing

Netbind
Mastery Level: 10
Skill Points Required: 30

Required Level: 26
Required Weapon: Unkown
Prerequisites: Blur level 2
Type: Active (Cooldown: 20 sec) (60 MP per use)
Description: Throw a web to binds enemies (up to 3 targets) movement. 3 secs duration at level 1, 0.5 secs per level (7.5 secs at level 10)

Affected targets can still attack. Targets struck by netbind cannot move, but they can still jump while they are binded by net (this is a bug). When in air, they can move around, making it possible for affected targets to bunny hop away. Netbind has a short cast time of about 1 sec, which is very long in pvp, hence it is not advisable to pump net bind for PvP. For PvE, monster will never run from you, so netbind is not required (unless you decide that some bondage is fun....).
In summary, netbind has a casting time of 1 sec, making it useless for PvP the effect is useless for PvE too, as monster doesn't run from players.
