I'd have to disagree, unfortunately.
A "halfway" build designed to PvP and PvE doesn't work for Elemental Shaman. You really need to decide one way or the other. Points are simply too precious and there are far too many talents to cover.
For PvP, Nature's Swiftness, Elemental Warding, Elemental Shields, and Eye of the Storm are completely mandatory in my opinion. Healing Focus and Totemic Mastery aren't
quite as necessary, but I still highly recommend them. Nature's Guidance is pretty much overkill for PvP hit rating, Imp. Reincarnation is completely worthless, and you won't
ever be casting HW in a PvP fight, so you're better off with Tidal Focus to make LHW a little bit cheaper. You won't miss Unrelenting Storm at all, nor will you ever lay ToW; your direct-damage fire totems are the weapons of choice in every scenario.
For a 40/0/21 build, you want something more like
this.
As you can see, even that build lacks Elemental Shields. It's really a difficult juggling act among Elemental Sheilds, Elemental Precision, and Tidal Mastery over in the Resto tree. You might be better off with 44/0/17 since crit gets hit so badly by resilliance, but... then you're missing the all-important Nature's Swiftness.
However... given some time you might eventually reach the same conclusion I did. PvP is not like PvE. You don't just stand there casting Lightning Bolts and Chain Lightnings over and over and over. If you do, you die. (For the record, if you don't you still die, just maybe a little slower, but I digress.) It's really pretty hard to appreciate or miss Lightning Overload in PvP since you really end up casting lightning spells a lot less frequently than you might imagine.
If you're at all curious,
this is my personal Elemental PvP build. All of the fixin's except for two points in Elemental Precision, and silence/interruption duration reduction from Focused Mind to boot.
PvE's much easier. You don't have to worry about constantly getting hammered on, so your build would work fine for that. The only thing I absolutely, positively recommend you do is pick up Totemic Mastery. You want the extra radius on your totems' AoE to benefit both yourself and your party members. It is absolutely mandatory in PvE for any spec of Shaman.
