What else would you use those points for anyways? Iron body or endure? xD
The only reason you would need those points for something else is if you go hybrid. And yeah, hybrid WKs are awkward and aren't fully hybrid (choosing one weapon for each charge). I would imagine a hybrid Sader to be awkward as well.
It boosts your damage (and for saders helps you gain orbs faster) so I think it's plenty more useful than the alternatives.
