I would much rather see rdm as pure casting dd. Not a trace of support in the job at all.
imo we have enough tanks, could add 23 more and still will be a shortage, bribing with mounts never works either se.
I say pure caster dd, not a support UNLESS the party setup changes to 5, to include 1 support job/party.
Unfortunately, many people react negatively to anything that isnt the fotm pure dd...It sounds good on paper but would be a nightmare for any poor soul that played it. It wouldn't go over well as people are in too much of a rush to complete raids/dungeons.
Out of fairness to any new job its gotta be only what we can sign up for now, dd, healer or tank.
(I really LIKE the idea of support mind you, I like the idea of a support rdm who can add some buffs, decently heal in emergencies, possibly even tank for a min or 2 if need be..and still do OK damage , I enjoyed rdm in ffxi

....BUT people wouldn't tolerate that unless there was a separate category for it made standard.
All we see is gogogogo now...this cant take 1 second longer!!)
More importantly though, I am not confident that se could design it well enough as a support to NOT influence the speed of a run for the "perks" or protect their players from the inevitable needless complaining from others ...People only look at damage numbers, not what benefits they may bring.
Just don't think its SEs strong point to make an accepted and useful support job, seeing most of the HW skill/spell changes and the new jobs.
But im still curious to see what we do get
