Been going 2x lone wolf mages just buffing up and comboing off eachother.
I have found playing from range to be generally superior to melee, as you get to let enemies come to you which allows you to reserve AP/not spend lots of AP moving. Get into a good position, chokepoint enemies with AoE ground effects, stun/freeze/slow for control and use whatever is the appropriate element damage for the fight.
The occasional boss that's immune to CC is annoying but can still be kited to some degree I've found.
