I must state, first off, that I have had the pleasure of bashing with Dingo on only a few occasions, but have been impressed with what little I know.
Since I am not a member of the Druid guild, but am a member of that class, I would like clarification on your post, Dingo...do you see Sentinels acting as "tree-huggers" to the extent of our brother and sister Druids?
Regardless, how the Druids approach their stewardship of the forest is no business of mine, unless it interferes with the Sentinel approach. That approach is not quite like what you portrayed in your post.
Scolding a bear for scratching his back against a tree? I think not. The Sentinel way is to protect the forest for what it is: the natural, living forest. A place where the circle of life is played out on a daily basis. We do not tell the lions not to kill and eat the sheep, for in so doing they cull the weak and help the sheep to become stronger.
We do not scold the fox for slaying the rabbit, for it does so only to feed, not to further some philosophical goal it has. What has somewhat gotten lost in this debate is that Blackleaf has said, indeed reiterated, that fighting and killing an animal is not what we are questioning.
We also do not scold the bear for relieving himself in the forest, even if it happens upon the poor head of said bunny. 'Tis unfortunate, but after all, we know the answer to the question: "Does a bear.....?"
To think that animals gain the freewill to choose to lay down their spirit for the enhancement of shrines, when so far only one example in the history of Achaea has been brought forward by Echo where an animal refused the sacrifice seems odd, does it not?
