Better notifications for Bard's Mage's Ballad procs

I'd be great if there were better visual feedback for Bloodletter resets during Mage's Ballad than a small blink on the job gauge. Or sound notification. When Repertoire from The Wanderer's Minuet reaches 3 stacks there is a sound for that. Would be great to have it for Mage's Ballad but softer, taking frequency in account.

I don't know if pointing at a other games is a good tone here, but WoW's Frost Death Knight procs visuals are fantastic. I think something similar would be wonderful for Bard.
