I still hope for - in the future - getting a class that can support like the captain can in lotro. it's still my favourite support role in any mmo I ever played (though pistols in TSW is fun too but usually combined with a healing class to just buff the player's healing -.-)
lotro's community didn't take the captain seriously at first, but eventually they were really high in demand. I can totally see that happening with changing bards to be more support-ish (again), or to give us a second supporter class that is an ACTUAL supporter. constantly buffing/debuffing/placing stuff/off-healing (or even off-tanking) can be quite a demanding - but also very rewarding job.
(aw, now I miss my captain)
edit: I played mostly whm/rdm in FFXI, but when I played my rdm I had a lot of fun with it. I could also see a second job for the archer being an 'actual' supporter, or maybe a job for the coming musketeer. the puppetmaster could be a support job (why not when bard is mostly a dps? :P)
of course there could also be the 'simple' solution of making the songs the bard already has a lot more useful. give mage's ballad a burst to magical damage, for example. (I always forget the name of the song for tp regen since I never use it, but that could give the enemy a debuff or something like that) swiftsong could lower the gcd (just a little, maybe .1 - .2 seconds) ....
