being a rdm myself, i wouldnt ever want to melee in pt, dynamis, or anywhere other wise where the 10-30 seconds i would spend meleeing, i could gain next to 100 mp resting.
but, i melee alot solo and my 'well geared' would go a little something like..
/nin
main: Blau Dolch
sub: joy
ammo: t.sting
head: warlocks chapeau (only cuz utsu casting so frequently, no sense in meleeing in turban)
neck: pcc (7skill < 10 acc when 200+ skill, esp. when taking about rdm melee)
ear: suppa
ear: Ethereal Earring
body: duelist tabard
hand: dusk (+1)

ring: jelly ring or rajas
back: shadow mantle or Umbra Cape
waist: speed belt, n.sash (lolAV)
legs: goliard trews or paluwan legs

/blu (mainly) /drk /war ect.

a rdm subbing anything is not going to be able to to beat any main class dd. the best they could do is be a semi blu, any without being able to self sc and having a high mp cost to damage ratio...get back and support heal =P
