Agreeing with most people that [Elemental Attunement] is better than [Attuned Was Songkai]. However, in places where enchant strips are abundant, it might be worthwhile taking a Rt/E with your build in place of the elementalist; then again, the Rt/E relies on an attunement as well.
Partially off topic, but while we're speaking about Elementalist skills; I think it'd be nice to see a few air skills take a slight change in PvE. for example
[Lightning Strike] - could also hit one nearby foe
[Chain Lightning] - could lose exhaustion and up to 15s cooldown for PvE
[Lightning Hammer] - could hit adjacent foes in PvE (it does the same damage as Rodgort's anyway, considering the burning on that and the AP on this)
Back onto the subject of [Attuned Was Songkai] I've found it useful for simply spamming, as another said, [Renewing Surge].
