Raid bards nowadays (and in the future)

[Bristlebard]

Are bards still as great to have around in raids now as they were before the 255 resist cap was put in? Do resist songs lose their power in Velious when players can get more and more resists on their gear without having to sacrifice other stats to do so? What other roles will bards have in raids besides resist songs and pumping mana for casters? Is it a big issue for bards that there are so many important buffs from other classes, not leaving much room in the buff window for songs?
