ya, I know VIT on gear adds defense and MND on gear will add cure potency(and magic defense?). So, they are still doing something. But VIT also raises HP and MND raises MP, both which do not happen if they are on gear. idk, its what the stats do so I feel they should do it, and really can't find a reason why they shouldn't. kinda cheapens some stats on gear IMO, especially on accessories.
