Can't figure out what to give up (talents)

[Siaea]

I mainly PvP on all of my toons, with my shaman team being first and foremost. I rely on insta Ghost Wolf heavily to get out of sticky situations (especially WG where a warrior can have 400k hps). This is what I've figured out so far:

but there's no room in there to get insta ghost wolf. You guys that are doing the shammy teams, have you come up with a nice build yet? I like the points in shock cool downs (my shocks trigger the hand rockets on all 5 toons, sometimes a one shot kill), and I usually try to avoid talents with procs for the most part because usually I try to keep them casting the same thing.

EDIT: Ugh...I just noticed they moved Improved Fire Nova to the Enh tree. Ghost wolf, 5 novas was my favorite way to AoE farm/quest.
