I ask the RDM's that don't want Cure V: what do you want RDM to be. Pre-ToAU we were refresh-bots to maintain the mages MP. Post-ToAU we were cure-bots that could maintain MP through the rapid fire TP burns and still adequately heal.
Post-Abyssea we are needed neither for curing (which we aren't good enough at) or refreshing (no longer needed with refresh atmas, subbable refresh and convert). We were never needed for enfeebles. We still aren't. We were never great at nuking. We are better but still woeful compared to BLM. We have never been great DD'ers and still aren't. We have been great tanks but that ability was nerfed a while ago.
So if you can't be an alternate healer, what role do you think you fit in a party? Or do you think we should just be happy in a niche of solo survivability? Jack of all trades doesn't work in this game. You have to be good at something to get into parties. For RDM that's always been MP management and Curing. Unless SE suddenly changes the effects of enfeebles, it will remain so.
