Why is BRD considered "support"

[AskaRay]

If people are reluctant to use songs when they need to then they are just bad bards. No decent bard would look at a healer who is soon to be OOM and probably cause a wipe and be like "man, I REALLY want to help you out bro but muh deeps!" It just doesn't happen.

Sing your gosh-darn songs, bards.
