Suggestion regarding BARD ability, Battle Voice.

I have been thinking about this for long time, mainly on fights where one of our healers (worse if it is the white mage) dies during a burn phase, and the bard is forced to do Mage's ballad while the party is struggling to meet the required dps needed to kill their target.

So my idea is pretty simple, make Battle Voice ignore the damage reduction and keep the double effectiveness from songs, like Mage's Ballad and Paeon.

Since it has such a high cooldown 300seconds, it can't be used frequently, maybe twice during a long fight. And there would be still instances where the Bard would be "forced" to use their song even if they do not have Battle Voice ready.

It could even be added on 3.0, as a trait for Bard that would improve battle voice.
