I've stated my points against Preservation being in Change multiple time in this discussion so I don't think stating them again will be of any use. I will instead ask you why you think they're wrong.
Irreversibly, not destructively. Not that it matter to your point
Other possible reasoning: giving something to someone change them
Aren't these two idea basically the same? Honestly I'd like your theory far more if you had Preservation in Bind, Whimsy in Change and maybe Autonomy in Think (autonomy imply the ability think for yourself)
That would be a great place for a Wisdom-ish Shard, yes.
There's more to be Valorous than just a feeling of courage (is courage even a feeling? I thought it was about how you reacted to fear not about another feeling) so imo she could be in Feel as much as she could be in Think
On the one hand if you're right about the name of the fourth Dawnshard being Bind, I disagree with this placement for the same reason I did to Preservation being in Change
On the other hand if the Dawnshard known to Bind mortal and voidish creature has another name it's possible Autonomy would be one of it's aspects (see my argument for Autonomy being an aspect of Control in my last post)
I don't remember that speech, when was that?
Is not an part of Change, it can be a part of Bind, of Survive or of Endure, but not a part of Change
Honestly Change is already a wide enough command without adding the "Don't Change" possibility
