From Unearthed Arcana (by way of d20srd.org):
Druid
The druid might choose to give up her wild shape ability in exchange for becoming a swift and deadly hunter.
Gain
Bonus to Armor Class when unarmored (as monk, including Wisdom bonus to AC), fast movement (as monk), favored enemy (as ranger), swift tracker (as ranger), Track feat (as ranger).
With a base 16 Wisdom, the AC bonus would be okay if you want to jettison the Wildshape anyways.
Going in a slightly different direction, you could combine this with the Druidic Avenger class variant and also add levels of Fist of the Forest from Complete Champion. I'd assume the Fist of the Forest levels would be 'non-associated' class levels for a Nymph?
There are also the prestige versions of Ranger and Paladin (base 19 Cha), both with 1/2 caster progressions (and arguably non-associated for the levels without caster progression?)
Of course, all of the forgoing assumes that you're willing to overlook alignment issues.
Druidic Avenger
Add Intimidate to the avenger's list of class skills. Eliminate Diplomacy from the avenger's list of class skills.
An avenger does not gain the service of an animal companion.
Fast Movement (Ex)
A druidic avenger's base land speed is faster than the norm for her race by 10 feet. This ability is identical to the barbarian ability of the same name.
Rage (Ex)
An avenger can enter a furious rage, identical to that of a barbarian. An avenger can use this ability once per day at 1st level, and one additional time per day for every five levels above 1st.
An avenger does not gain the greater rage, indomitable will, or mighty rage abilities.
Spontaneous Casting
An avenger cannot channel stored spell energy into summoning spells.
Tireless Rage (Ex)
At 17th level and higher, an avenger no longer becomes fatigued at the end of her rage.
Wild Empathy
A druidic avenger takes a -4 penalty on wild empathy checks.
