Much better deal than the 110 gold for the dryad... which has one nature.

The Dryads are also Sacred, Holy 3, stealthy, Awe +2, +10 leadership, and +3 magic resistance.

Holy 3 by itself is pretty expensive, (e.g. Voice of the Lord), and the other abilites combine to make Dryads much more survivable and utilitarian than Witch Doctors. Sacred means that in the long run Dryad's are actually the more effecient researchers (especially w/ a magic scale); not bad considering that Witch Doctors are one of the better researchers.
