Priest+Mage are probably the best combo. In a good team you can kill 10-12 mobs at the same time. It's important that you keep a cool head if the priest gets attacked by a mob, when you pull it. The priest can cast shield on himself. The mage has to wait till all mobs are in range of the IAE and then he can start spamming it .
Procedure:
Priest casts HoT on the Mage
Collect mobs
IAE with priest side by side(don't heal yet)
IAE, priest casts shield on mage
IAE, now the priest can start healing the mage
The mage could cast from time to time CoC so the speed of the mobs is reduced the half of their speed.
If mobs try to run away cast FN.
If the mage gets low on HP, blink or FN, go on distance and let the priest heal the mage.
Then move on.
The priest HAS TO cast the fastest healing on the highest level.
Priest casts shield
Priest+mage run and collect mobs with their mounts
Priest casts HoT
Priest spamms his fastest heal
If the mobs have little hp
FN(the priest now knows that he has more time to heal)
CoC(50% higher crit!)
IAE spamming till every mob is dead
