Its a good idea. The questions need to be thought about though. A lot of questions listed above seem to be about how characters died; what they observed; or what they went on to do with their lives.

What happened at Hogwarts towards the end has been described as a war. In war there are casualties.

What we also have to understand is that this book and the others that preceded it were written from Harry's point of view. We only get to know what he saw and what he was told. We can't really expect him to be everywhere .. to observe everything.

I do think however, that perhaps a part of the epilogue should have included some details of who went on to do what .. especially the main characters.
