It is a Frost/Arcane spec. Great Frost offensive spec. From the arcane tree you have arcane concentration which makes you occasionally cast with no mana needed, along with the mana reduce from the frost tree, you will not waste your mana as long and keep casting. Water Elemental is great for both PvP and PvE. For raids it will output additional damage from you, without giving you the hate. For PvP the ranged frost nova is extremely usefull. The 70 Spec is also for AOE farming as you have Cone of Cold and Blizzard maxed so you can use its fullest potential. Hope that helps.
