Warlock & mage spec?

[dimzen]

Hi,

I have a walock and a mage I wanna lvl from lvl 65, so why not dual-box them?
But.. what spec's are best for the two?

Was thinking to have this spec for my warlock http://www.wowhead.com/?talent=IZ0xIzsgMi0sgzbZE , so they have a tank with them

IMO demonology + fire.

What he said. felguards are awesome, and will keep mobs off of your casters. The mage can do some additional CC, if necessary. Throw in a priest, pally, shaman or druid and you have an awesome setup

Could you like a mage build for a lvl 65?

I was thinking more of frost, because imp frost bolt and imp shadow bolt have the same casting time
