Hmmm... I think I am going about this all wrong.
Try this on for size.
Melee Rdm = Person playing the role no one wants but the Melee Rdm.
Now before you go frothing at the mouth... Think about it what a 'melee Rdm' typically is. It's some person that wants to be up in AoE range with some kind of melee sub doing physical damage to a mob; while a group needs a healer, enfeebler, and/or nuker.
What groups don't need is some guy distracted by how big his Vorpal Blade is...
If you're going to support your party properly you are better doing so at a distance. If you're going to melee, you will be too distracted to support your party. You could be needed to cure someone and get AoE stunned. Or you could be Weaponskilling when people expect you to cure. Or you could be the complete opposite, and be curing, enfeebling, nuking so much you're not meleeing. AND if you're using a melee sub, you're cutting into the resources to do the expected roll for the group.
Any way you cut it, it's just impractical.
