If you risk getting targeted, Demon Skin is obviously sick.. Otherwise, the extra peels are good. Howl vs melee cleaves (or stacked teams), Coil vs other teams.
Contagion might be prefered in arena, at least if you're going for spread damage (in 3s mainly). Vs. stealthers (and bgs) I find Absolute Corruption very nice (mainly in 2s).. Makes it a pain for rogues to try and get a restealth when the 2v2 ends up being a 1 on 1. I think Contagion will be my go to talent for arena though, especially with Endless Affliction from the pvp talent tree later on.
Soul Conduit is most likely the easiest choice for 3v3 and bgs (not always the best though), for 2v2 I'd go Soul Effigy, and in some cases in 3v3 as well.
Those are my opinions at least.
