While not a bad product, I feel it's a bit misleading. None of the new subclasses are really designed around giants, and are more just generic new options. The spells are also not really designed around giants. The only thing in here that is really flavored towards a campaign geared towards fighting giants specificlly is the magic items. So, while worth the buck I spent on it, I feel calling this "Giantkiller's companion" is a cheap way to tap into people's new interest in the newest WOTC campaign release.
