Larian seemed to think people's complaints about Warfare was only that Warfare offers fractionally better damage, but that's wrong.
The biggest problem with Warfare is that it unnecessarily kills build diversity by making 6 other skills not worth investing in (excepting skill requirements) until after maxing Warfare. It is troubling that they did not realize that after all this time.
I think Warfare would be in a better balanced spot if it didn't apply to Bows/Crossbows, Daggers, and Necromancy.
