I must admit I don’t think about these classes much either, so I don’t have a lot to say about them. I definitely agree with the idea that sylphs misapply their aspect, and that bards only reject theirs initially and embrace it later. Your prince analysis is also in keeping with my interpretation. However, I believe that princes require a bit of a deeper look, given that it is the most contradictory class.

In my view, Princes, as the most contrary to their aspect a. have difficulty fully connecting to it and b. they destroy their aspect in others when they cannot get it for themselves. They direct their negative self-image outwards, to where they see themselves (their aspect) in other people.

-Hope, I think, is about creative potential and building things up, planning for the future. Eridan’s plans, as a prince, take a destructive tone, but he still (misguidedly) believes he is working for the advancement of his race. By exercising this hope, he destroys the hope of all others as he misguidedly kills the angels in his land, believing without reason that they are evil. An important distinction, in my opinion, is that while he seems at first to act like a rage player, he is acting in a hopeful way from his perspective, and his motivations are geared toward advancement, not tearing anything down as would be seen in a true rage player.

-Dirk has a healthy dose of self-loathing related to his poor emotional life, despite being a heart player. He is aggressive in his relationships, and he destroys the heart (emotions) of all his friends, as his pairing with Jake leaves Jane and Roxy without a suitable partner in their group. In this way he destroys heart, destroys through heart, and is destroyed by heart.

Anyway, I just wanted to add my personal interpretation; your explanations of the classes are great as usual!
