Sigh. I figured people would eventually drop the RDM thing, but I see that is not the case.
Trying to make "support" the whole point of a job is not and has never been a good idea. This is why design in general eventually moved away from needing classes to specifically act as mezzers (and refresh bots in the case of FFXI) and in turn do what you just mentioned: baking certain aspects into existing roles. Being the guy that's there to only interrupt, or only sleep, or only stun, or only para/slow in the case of RDM isn't much. To those of us that know the class for its various aspects, it's certainly a downer to see only one shine through and the rest tossed to the gutter.
So you forgot my response to your question:I do notice that nobody bothered to address my question either, funny how pointing bloody fingers can backfire on you sometimes. What would you have them remove from RDM to get what you want? And yes I said "remove" because RDM is extremely powerful, even if this has been dimished somewhet by Abyss.
Bolded for emphasis. A nerf to switching roles on the fly, but maintaining access to a reasonable level of versatility while on the field (I'm open to discussion on what would be considered reasonable). And yes, that's a huge part of the class as is to remove while keeping the current curebot role. The bonus comes in making a second role available and relevant outside of soloing. It's a win-win.
