On that I disagree.

A War Wizard is someone who, rather than specialicing in one or a few fields of magic, has an aptitude for everything... not just many, but ALL fields, including prophecy, which by itself is already very rare.

War Wizards also access their powers differently. Instead of consciously accessing the han inside their bodies through study, meditation and so forth, a War Wizard accesses his magic through his emotions.

Those are the two definitions that were given by the books and neither is dependant on substractive magic.

It's true that no War Wizard was born in the time when the substractive was sealed up, but they were extremely rarely born even when the gift was still whole. If you keep in mind that only two prophets were born in over 1000 years and that War Wiazrds were even more rare than prophets, it could very well have been chance that those 3000 years didn't see any WWs born.
