56/10/5.

With the awesome deep elemental talents now, I don't think the 51/0/20 spec is the only way to go anymore. Especially since they moved totem mana reduction to tier 1 resto.


Edit: And insta ghost wolf is massively useful in all forms of pvp.
Edit: 5/5 unrelenting storm has good synergy with +10% intellect.
