Being a frost mage myself, i can dps just as well as flame and arcane mages if u do it right and u cause less threat then flame mages which i think is best for pve. The icy veins causes ur spells to be uninterupted and hastens. Being troll race as well allows me to utilize thier race feat as well with veins drops my cast time for frostbolts to around 1 sec. and not completely geard i deal almost 5k crits like every other bolt. Really just matter if u want to work hard for dps or be lazy and expect it to be handed to u. If u a good mage u can dps frost just as good as flame or arcane. Just ask my guildies. Plus it really matters how u gem ur gear as well.
