warfare multiplicatively scaling all physical damage (including that from necro spells) almost looks like a bug or a rash last-minute decision, because it doesn't make any sense balance-wise. it should only scale warfare skills, and weapon damage should be scaled (multiplicatively) by the appropriate weapon ability. this way as a warrior you'd pump str unconditionally for additive bonus, but then you'd have to choose between 1h and 2h for a larger multiplicative bonus, and put some points into wf for high-tier skills, instead of just dumping everything into it.
