if you want to melee on rdm then get an almace. then level Blue mage because it's WAY better. Rdm was an awesome solo job (kiting or melee) until blue mage could solo hard NMs. this happened around level 85. if you want to play like rdm used to, LEVEL NIN.

Rdm has a good niche right now, its not worthless. Go to Voidwatch! you will mostly cast Addle, Slow2, and Paralyze (whenever it works, i think never). Blind will often land and Bio3/Dia3 can help a little too. Mostly though you're a proc whore. and Rdm is really good at this because of its huge Fast Cast and you can even Nuke during Blitz time.

also you can help heal so your alliance doesnt whipe. you can raise so the whm doesnt waste an hour trying to cast raise while the pld is dieing. and you can throw haste/refresh2/protect/shell when needed. i spend most of my time working on triggers and only throw refresh2 on the whm (unless im in pld party). but please dont melee in Voidwatch!!
