Description:
Druids are seekers of justice, and nature's defenders. They protect the
environment with a fierce passion. Their ability to use natures given
components to fight injustices make them formidable opponents in both
physical and mental disciplines.

Description:
The reavers are a dangerous, possibly insane religion that thrives on the
death, destruction, pain, and suffering of others weaker than themselves,
while at the same time insuring their own survival. They roam the land,
smashing art, murdering families, and burning down villages. Nothing is sacred
to a reaver except himself and his sacrifices to his dark lord.

there is a contradiction there, don't you agree?

From a minmax-gameplay -point-of-view your point makes sense. However from the
fantasy-realism/roleplay -point-of-view it hardly makes none.

Just my personal opinion, though.
