one of my things is that Magic can't cure everything.. like a missing limb.. or breathing problems.. makes it so much more realistic..
and you've taken points of contention.. such as when Kartkoff voiced that Severus' was a Death Eater in front of the entire body.. with Dumbledore vouching for him... it was wonder anyone trusted him..
Filius as a the little giant that no one thought would be devious.. excellent..
