Criticise my Shaman PvP build

[Omega]

Since Shamans are a Jack of all trades, there are many Talent builds out there, so I'm wondering if i could get some criticism from you guys for mine, its a 22/7/22.
Elemental
Concussion-5/5
Convection-5/5
Reverberation-5/5
Call of thunder-5/5
Elemental Focus-1/1
Elemental Fury-1/1
Enhancement
Ancestral Kowledge-5/5
Improved Ghost Wolf-2/2
Restoration
Tidal Focus-5/5
Totemic Focus-5/5
Combat Endurance-1/1
Improved Lesser Healing Wave-5/5
Tidal Mastery-5/5
Natures Swiftness-1/1

So I think this is a decent build, however my question is would it be wise to take one point out of Reverberation(4/5) and take 2 points out of improved ghost wolf(0/2) and put the 3 skill points into improved Lightning shield? I've heard that ghost wolf is very useful for pvp and getting out of bad situations.
Thanks to anyone who helps :)

To be honest, I don't use imp. ghost wolf at 60 anymore. 1-60, sure it's great for certain situations but they're just too far and few now. After my talent change I can't say I'm missing it.

The Enhancement AK 5/5 and IGW 2/2 seems pretty common, I just think you can put those 7 points to better use.

combat endurance is retarded.

If I were to get rid of Improved Ghost Wolf, where would you suggest I put the points? I wish i could finish my Elemental tree off with Elemental Mastery but I'd need more points than just the 7 I'd get from enhancement.
Also, I've heard combat endurance makes a difference in fights, howcome you say it's retarded?

[evilution]

its like 3-5 hp a tick ...

I've never been in a fight where that would have made a diff

[Hogart]

Troll with Combat Endurace, that have to make a diffrence with Sta/Spi build ? :)

[evilution]

troll and combat endurance suposedly do not stack

[Hogart]

When i play troll shaman they do stack.

[Firecrak]

They do stack, Combat Endurance is pointless and worthless. It may negate a warriors Rend...and thats about it.

Take 1 out of Combat Endurance, and drop it in reverb 5/5. Your shocks are your life in pvp.

While I do agree, GW is a great tool pre 60...I am finding I use it less and less and less. Its only useful for herb picking...if that, most times I can keep people in range with level 1 frost shock if they choose to be a pussy and run.

EDIT: On the issue of AK vs Shield Spec...if you aren't going deep into Enhance, and aren't getting 2hd, might as well put 5 in SS...5% mana is fuck all. It may be enough for 1 heal at 60, if that.

If you like challenging groups of enemies, IGW is a good skill to have =)
