Yes there is, what the unwantedbeing said could for clarity had been done with a quote;
"Giants do not attack in the same way as other creatures..." (Warriors of chaos, p.65, because that was the book I had within reach)
That there is "no universal truth in warhammer" might be true, but it doesn't automatically mean everyone and his dog's opinion and interpretation of the rules is correct...
And in this case; you are wrong. You are free to play however you like, but don't argue that you have a valid interpretation of the rules in the book, because you don't.
