Input on a shaman build

[Vahz]

I'm getting a better a feel for shaman builds and have been playing around with some of the talents but I would like to ask the Nurfed readers on their input.

Currently, there are only two types of builds I'm really considering but am obviously open to suggestions.

The first is: 21 Restore, 7 enhance, 23 elemental

5% less mana cost for heals
10% less mana cost for totems
75% non-interruptable Lesser Healing Wave
5% healing/lightning crit chance
Nature's Swiftness

5% more max mana
2 seconds less for ghost wolf

5% more damage from shocks
10% less mana cost for shocks
0.8 seconds less cooldown for shocks
2 less seconds for fire nova totem
Clearcast
6% crit chance for lightning
100% crit bonus from nature spells

This will allow me to play the role that I like with the shaman as a healer/totem pusher/nuker. The other suggested talent setup would be to ditch the 7 in enhance and go further into the elemental tree.

I recommend 30/0/21 for group fights

Interesting.

How would you place the points in Elemental?

In order to get Lightning Mastery, I would have to place a single point to unlock that talent. Where would that 1 point go? Imp Lightning Bolt?

5 Concussion (5% more damage from shocks)
5 Convection (10% less mana cost for shocks)
5 Reverberation (Reduces shock cooldown by 1 second)
1 Elemental Focus (10% chance for Clearcast)
5 Call of Thunder (6% crit chance for lightning spells)
2 Imp Fire Nova Totem (Reduces time by 2 sec for fire totem to activate)
1 Elemental Fury (Increases crit bonus by 100%)
1 Imp Lightning Bolt (Reduces the mana cost of Lightning Bolt by 3%)
5 Lightning Mastery (Reduces cast time of Lightning and Chain Lightning by 1 second)

I think it might be a better idea to ditch Imp Fire Nova totem (since I plan to be in the back) and throw 2 more points into Imp Lightning Bolt with reduces the mana cost by 9% instead of 3%

depends on usage and playstyle.
If you find yourself burning through mana already you might better get imp lightning bolt, if you have plenty mana and you cast a new nova totem all the time and the reduced cooldown really helps you, get that instead.
It´s like, extra burst vs mana conservation.
Both are ok imo, depends on your gear and playstyle which is best tho
