Fonewm can be pretty competent with weapons too, but even if you are using a tech only no attacking setup, there is still always something more useful to put in your armor than a unit just for stats; having free slots is always good. Maybe you want a cure/shock | cure/freeze | cure/paralysis in there, or a trap/search, or a heavenly/technique, or a heavenly/hp, or a wizard/resist, etc.
