I'm doing some additional Theory Crafting (doesn't that term from from Warcraft? Shouldn't it be Theory Questing????).

Warden Spec - Druid Tree, in order
STR - 4, 4, 8, 8
AGI - 4, 4, 4, 8
STA - 4, 4, 8, 8, 1

70 Points

Warden Tree - In Order
5 points in each of the 4 Strike skills, Force of Nature
5 Enhance: Resurrections, 4 Enhance: Numbing Spores, 5 Enhance: Spirit of the Bat, 3 Enhance: Protecting Grove, 5 Enhance: Death Interventions, Reformation
5 Enchance: Root, 5 Enhance: Spirit of Wolf, 5 Enhance: Willow, 5 Enhance: Undergrowth, 5 Enhance: Protector of the Forest, Nature Walk

70 Points

This maximizes your DPS and allows you to heal while DPSing. Combat Arts have .5 second casts, allowing you to be DPS effectively while casting your HoTs. The AGI and STA lines encompass all the necessary skills for improved healing.

Dirge Spec - Bard Tree, in order
STA - 4, 4, 4, 8
WIS - 4, 4, 6, 8, 2
AGI - 4, 1
INT - 4, 4, 4, 8

This is as far as I've figured for Dirge. Most importantly to a melee group is the 8 points in the STA line for Fortissimo, which is a group buff giving +10% Double Attack chance and the WIS End-Line ability, increasing your groups Crit chance for melee, ranged, CA and Spell by 7.5% across the board.
