I have 5 Level 18 Shamans at the moment and still have another team I retired that has a Level 28 Prot Pally. I'm thinking about replacing my main shaman with the prot pally but am not sure about it.

Does anyone have any arguments for or against this idea? I am interested in long term more than short and am thinking a prot pally could be a huge asset. Farming with a prot pally can be pretty awesome as I have seen on youtube. It can also help keep things a bit more controlled and focused, me thinks.

Thoughts?
