Druid's Friend of the Weald-
I want to suggest that this passive root skill, gets some kind of benefit that helps the Druid out directly.
maybe something like
= = = =
Increase the effect of Balm of the Woods by (X)% for every point spent in the druid tree above 36.

Increase the damage and effects of Spirits once every 30 seconds, by (X)% for every point spent above 36 in the Druid tree.

Increase the amount of damage absorbed by Shield of Oak by (X)% for every point spend in the Druid tree above 36.

increase damage of Bombard by (X)% for each point spent above 36 in the Druid tree.
