unfortunately your all forgetting one key aspect. for rdm to become a job it has to be based off a class.
that class will be fencer. The way you want is never going to happen in this game. Fencer will be melee with
some CC skills and Rdm will just enhance that.

I myself can live without the elemental magic as long a fencer/rdm can be effective at melee and seriously limit
mobs abilty to function i'm happy.
