First off, sorry if this has been made before, but I couldn't find anything in regards to this

I'm starting to get into Pvp at level 90 now, as a Resto shaman, and would like some tips on to get started.
Really just gonna be doing some BGs to start with and arena for giggles, but hoping to progress with time.

As of current I have the entire blue scale pvp gear for shaman (the intellect one obviously) but unsure on enchants etc, and optimal glyphs, talents, etc.
So if someone could help or point me in the right direction, that would be great.
