Suffice to say, terms like "basic build" and "questionable rules" are wide open to interpretation. The improved weapons rules at the back of Complete Warrior that serve as the entire basis for coming up with millions of d6's of damage seem questionable as all get out, since the "1d6 per 200 lbs" progression is pretty self-evidently not designed with infinite scalability in mind. The hulking hurler is a more of an abstract exercise than a practical class that actually gets played. Will a character have a quiver full of 10-ton object to toss around? Probably not.
