Jesus Christ. /whm loses berserk, 1 attack up trait, warcry and 10% DA(which is really just 5% as joyeuse will overwrite it on half of your hits anyway). Do you stop meleeing and WSing when berserk and warcry are down? No? Then shut the fuck up. There are times where /dnc is superior and times where /whm is superior, /dnc's major flaw is inability to -na people in an efficient manner(be it because they're in a different party or because an aoe debuff just landed and your recast is awful on samba compared to the -na versions). Everything depends on your other member's playstyle, jobs, and what you're doing.. there are certainly times where it's worth meleeing with /whm over meleeing with /war to gain another person who can do -nas.
