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

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.

/discuss :)

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.

they should have made the GW talent top tier 8(

These new talent trees are so simplistic as compared to the old, I am sure in a week we will have them all down to thier optimal templates for boxers. My shaman are going restro (using fire mages for dps) so ....

I'd probably drop Convection, for Ghost Wolf.
But you're right, it's not an easy decision.
