Bah I prefer putting like 5 points in warmth, max blizz , glaicial spike , cold mastery , put some points in tele , static , energy shield and there you go.
For the equip i suggest
helm:shako or nightwing (depends if ur pvm or pvp)
Armor:Tal or coh (depends if ur rich and pvm or pvp)
Gloves:upg chancies or upg frosties(depends mf or pvp)
Boots:wtravs
rings:SOJ and raven frost
ammy:Mara or tal (depends mf or pvp)
belt:arach or tal(depends mf or pvp)
anihilus and cold charms should boost ur dmg around 6k + mastery = pwnage
