Except that the entire McCall house was rigged out with Mountain Ash wards set by Deaton (a druid). Melissa was merely needed to complete the closing of the wards could not be done by a supernatural creature. Thus it could be construed that the Ash went into place correctly because of Deaton's spell, and not Melissa's belief. This is different than the situation at the Rave, where Stiles had to ward the entire building himself, without any preparatory work on the building by Deaton of the sort he did at the McCall house.
