From John Sander’s paper Be Wary of Ware:

Today, there are exceedingly few evangelicals who are actual classical theists, even though they continue to use the title of themselves. Though Ware classifies himself as a classical theist, he rejects the traditional notion of immutability. Wayne Grudem rejects impassibility as being clearly unbiblical. Millard Erickson says that “the traditional doctrine of impassibility is not the current one” among contemporary evangelicals. These thinkers have modified classical theism in ways that Aquinas and Calvin would find logically inconsistent. The great classical theists understood that it was a package deal, you cannot change one of the attributes without affecting the others. When you begin to pull on the thread of a knit sweater, it will eventually unravel on you. So, beware of Ware, for his minor revisions to classical theism will, mutatis mutandis, lead to many more alterations.
