No they weren't. They were always very very powerful front line fighters. Most debuffs were completely ignored in early final fantasies and buffs were only ever necessary in boss fights.
So you want a very very powerfull frontline job, that gets nuke/heal/buff/debuff skills. This will never happen, if they implement RDM it gotta be a backline job that actually does the same it allready did in ffxi and not more.

Most ppl that want RDM, want a overpowerd solojob they can kite everything to death like it was possbile in FFXI but i doubt SE gonna be so stupid doing this again.
