As for talent choices, it's difficult, Swelling Waves is still good if you're fighting other casters simply because you get a lot more sustain.
Spectral recovery however grants a bit more mobillity and is quite decent against slower melees, also has a bonus if you can predict long stuns (such as HoJ) you can just sit into GW right before and heal for ~9% during said stun.
As ele, i'm torn in random bg's between these two, both have adantages.
