Shaman Spec for Outlands?

[Bellator]

Just one level away from hitting the Outlands with my Shaman. I still solo about 50% of my game time and currently going with Enhancement/Elemental spec. I've been pretty satisfied with this making soloing easier, for me at least.

Would it be beneficial for me to change the Shaman's spec for the Outlands? Taking into consideration the solo time verses the group time!

Thanks for the input.
