RDMs still have their place. The one thing they do well is enfeebling which earns them a spot in endgame. Since they are the best at enfeebling NMs and bosses. With the new high value magic accuracy weapons, the club, and eventually staffs coming, lets you use a lot of different gear.

RDM is a mage at its core, if you guys want to melee I would play a melee job where that is their main purpose.
