i am wanting to build my mage to be used in pvp but don't really understand the builds and don't know what build to go with. i was thinking of either going full frost or a frost/arcane... or maybe even a frost/fire. i am looking for survivability while still being able to get some pretty big crits. if someone could point me in a direction it would help alot.
Well, I don't know what level you are, but there are elemental build and arcane-frost and full frost (arcane fire and full fire too) builds in the FAQ.
Let us know if you have specific questions about a given build.
