If you want discuss the future of Bard sure but that's a different thing to what they are now. You may feel like a support but the dev team say otherwise.

Well Haste song is a definite no, Yoshi has already said they won't give haste to the players. Resistances are a SCH thing I don't think they'll give it to BRDs, HP regen already exists in the form of Medica II. I mean all well and good that you have ideas but until they actually make Hybrid role a thing (it isn't atm), there won't be classes that have more than a few select 'support' skills.

I brought up mnk earlier as dragon kick reduces the damage dealt by int based skills form the boss, which if I remember correctly is most castable things. Mantra increases healing done by 20% and almost every raid fight has an ideal moment for Mantra whereas that isn't so for bard songs. So Monk in current system has more utility than bard song, it still doesn't make them a hybrid or support for that matter. Could they be in the future? Sure, just not now, and not soon. Since 3.0 is a good 6 months away and we know it isn't happening there either.
