What rank are you in pvp currently? If you are below rank 7 or 8 I would highly recommend using a bubble spec. 7 - 10 i have other recommendations.
For low rank pvp bubble spec is a must if you don't want to get melted, if you are exceptionally skilled that's another story
Bubble build
To use fangs properly you need to be adept at tab targeting, which basically means you need to be able to target the right enemy at any given time. If you can do this then fangs is fantastic. Below is my current build for pvp.

Some tips
Fangs works on rangers as well as any melee class. Does not work on magic users unless they are trying to wack you with their staff
Static blood is great, I use it often, it changes elec dmg you do to healing for yourself. makes you more tanky. Plus it does retributive damage meaning the guy hitting you is hurting himself too.
power of the serpent ring is great for negating assassin detonation. Just use it whenever a sin starts hitting you, most of the time they'll plant the bomb on you right at the go. just fyi you do not need to expertly time this. It will negate the sins detonation as long as you hit it once the sin casts grim corruption on you which is usually their opener attack, Like i said most times sins will plant the bomb right then because bomb has a 5 second timer before it goes off, If you use potsr after bomb is planted during the countdown it will negate the explosion regardless, good sins will wait. Just learn who you're dealing with and adapt.
empowered life of set amps up your dmg every time you cast a heal
Rousing shock is a must have for obvious reasons
3 points in stun because the more you have the longer they are stunned. im sure you know all of this but for any future tos hwo may be curious.
For AAS I use the following
Chromatic warding rank 5 <-- makes you tankier
Field of war rank 5 <-- This increases your base dps and you can literally feel the difference when it's removed.
Deliverance rank 5<-- duh
Steadfast faith rank 5 <--- i am the only tos i know who uses this in pvp, It is not just for pve. Stripping elemental debuffs makes you harder to kill.
Constriction rank 5
Lull rank 5
Any player will tell you how much maxed stun with constriction sucks for them. It ends up being like a 15 second stun/snare if not broken
Lull lets you run around with eye up and once you get that up you can become a wrecking ball.
Let us know how you fare.
