I have asked some question on pally/mage... and i am currently playing a pally/mage pair..@ lvl 51..

i spec prot for my pally and frost for my mage.. i find frost for my mage could do quite some dps and the initial part is not too hard and compared to fire, frost produce less threat. Till the pally gets righteous fury and righteous defense, its hard for pally to keep aggro. Therefore, i think frost is the way to go.

esp when my pally is going in to mob groups, my mage simply juz stand behind and cast blizzard..

this is my setup for pally/mage.

- pally goes in and tank a group of around 5, starts with a hammer
- at the same time, mage cast frostbolt
- pally cast Consecration
- mage cast blizzard all the way

if my pally lose aggro, i will use righteous defense.

for me, its quite fun and fast since my mage could teleport to cities and at 40, teleport the group over.

hope my 5cents helped. :P
