Enhancement shaman no longer gain spellpower from intellect or spellpower (as strange as that sounds) , Instead 55% of their agility counts towards their spellpower. as of 4.3

This is wrong, partially. Enhancement Shamans no longer get spellpower from other effects for ONLY Enhancement spells. That means non-healing, ele spells. For Healing/Ele spells, which you use a fair amount in this bracket, spellpower still helps.
