I'm a bit iffy on it's gear recommendations for Enhancement Shaman but otherwise I'm really liking it.
I tend to go with Warcrafter.net and an EJ recommended DPS calculator when working out gear options.
Yeah, it's a little subjective. It reccomends Ancestral Knowledge for raiding resto shamans when every raiding resto knows that 0/5/56 is comparably horrible to 8/0/53.
But for the most part it works very well. Makes officers jerbs somewhat easier.
