I know the feeling. I'd LOVE to play as a RDM. The support from buff/debuff would be great rather than random DoTs with added effects. However, that's why my secondary job that I play is SCH. It's nowhere near what RDM is but it puts me to mind of. It heals well, casts buffs (Galvanize/Whispering Dawn/Skill&Spell speed buffs/Silence), while also being able to debuff (virus/disease/slow...) plus all the available DoTs (Bio2/Miasma/Bio/Aero/Miasma2/ShadowFlare).

Like I said, NOWHERE near a RDM but it fills the gap, for me to an extent, until it's released one day.
