So I played around a little more with the hybrid frost/arcane spec and my dps is at about 60% of my destro lock. I just respecced full arcane on the mage to see the difference and will report back later tonight. I wiped twice in Nexus (my team is lvl 73 and so should have face rolled this) on the last boss simply due to not enough firepower, hopefully speccing arcane will bring the mage in line with my lock and ele shaman which are both putting out similar numbers (lock is about 150 dps ahead but that is close enough while leveling )
