It's the same situation and history as damage shields, perhaps more so. Damage shields have been addressed in ToV. SPA 286 needs a huge boost to make them viable songs and abilities, providing flat damage.
You're right, I probably restated my understanding of his post at the time a bit too strongly than he (or I now that there's some time since the discussion) intended. Nevertheless, the issue of a whole slew of bard "adps" songs being essentially worthless persists. I will stand by my assertion that in 99.9% of situations, bards can play aria, have aura up, and then just do insults and dots and be optimizing overall group (or raid) dps output.
