Doubt any shaman would give up their Anguish gloves for these unles they are just tottaly 'jonesing for that extra leet cold nuke damage and a few hp's. /wink
I could do without the enhancements of these gloves and stick with spirit seared or even Kanleku's, as these are useles for anything but a desperate hp upgrade over the utility of both the forementioned pairs.
dont know what shaman would still use wisilks. not a huge upgrade between ahnaukals and wisilks as far as healing power/mana go, but biggest diference is u can get GoRM from ahnaukals but only GoM from wisilks. Also by this point you should have a better healing focus.
