The three minute abilities of the arcane tree also let me dump on up to 5.5k (I have 943 spell damage) frost bolts on unsuspecting allies in PvP.
This is insignificant compared to the power of the dark side of the force.
Wait.... wrong quote.... sorry.
You have a specific combo as full frost that will hurt more than a POM Frostbolt in PvP. Summon water elemental, start casting a frostbolt. When the frostbolt is just about to leave your hand, have the water elemental freeze your target and you cast an ice lance. The waterbolt,ice lance, and frostbolt will all arrive within .5 second of each other. I've been the recipient of this (as well as a giver of this) and you can see massive damage there (I got 8K in damage from that combo).
So, your average DPS as frost is supplemented by a water elemental, don't forget to use it when it is up. Along with winter's chill and empowered frostbolt, you can rock the DPS more as deep frost than as arcane frost once you get over 700 spell damage, AND still be viable for PvP.
