:: Rng / Ele :: Support Build - Need Help

Currently Lv14 almost 15.
This is my current setup.

Hunters Shot
Determined Shot
Read the Wind
Poison Arrow
Troll Insurgent
Healing Spring
Inferno
Firestorm

Its been working well. The role I tried taking was more of group support. Running in behind tanks when needed and using Healing Spring.. and firing off Inferno.

I have a decent Longbow. 14 - 25dmg with Poison mod on it. Thats why I have *Poison Arrow up, plus Its pretty powerful against single targets. What Ive been doing against single targets is ( starting with Poison Arrow, fire off Determined Shot, followed by Hunters shot. Then Into Read the Wind. )

I like having the healing spells up, they have saved my group and me on a number of occasions.

Im looking for some advice or thoughts on this build.
Thanks ~
