I would switch to elemental at lvl60-61 cus there are alot of good gear and trinkets u can get. I switched at lvl 60 to elemental and got some good quest items and spent around 50-80g on the rest of my gear. And let me tell u that i have never looked back. Im lvl 65 now and can take on 3-4 outland mobs with ease and only using about 1/4 to 1/2 of mana. they key is mana spring totem and mana shield spam. THis is wat i cast= round up 4 mobs (elemental mastery,chain lightning,fire nova,lightning bolt,magma totem, chain lighting, mabey another fire nova totem) bam 4 mobs dead with very little health loss and mana loss. just make sure u have mana shield up 100% of the fight.
