Yeah, Harry Potter book 4 broke the rule of "mixing up the thing that should be used rarely". In book 2, half the plot is brewing a poly juice potion to disguise the heroes as someone else. In book 4, the villain uses it without any of the difficulties the kids had. Also in book 4, a villain kills someone, transforms the corpse into a bone, and buries it. It feels so cheap and lame. I was unsatisfied with book 4 in ways I wasn't in any of the other books. I heard she got stuck on it and had to rewrite it, so that's probably why.

Well, a master wizard might be more adept that some third-year students. But, yeah, there were serious flaws in that one.
