Ench / Druid is good.

One of the best utility classes? necro's, so add them to whatever you want and it's a benefit (pulling, dps, tanking, mezzing, then to a lesser degree healing, mana dumping, also they get a rez later on, making them immense)

Monk / shaman has always been a popular combination, monk's can tank anything effectively once it's shammy slowed, shamans can heal, dot, buff, sow etc.

Mage / cleric can duo virtually anything.
