I'd agree that Dynamis appears to have been written purely as a method to justify the Sundering which is pretty...questionable in itself. An excellent way to showcase whether something is or isn't acceptable would be to subject the protagonists to that very same scenario. If they seek to resist or do not enjoy it then that says it all.

How unfortunate, then, that they're never at risk of any harm befalling them in the majority of cases. A fact many of their fans know all too well, I suspect. So it's pretty easy for them to shrug in indifference because even when one of the allies to the protagonists such as Hydaelyn does something messed up it's never going to be aimed at the protagonists so in their eyes it doesn't matter.
