The nerf on Inspiring Tune ironically makes it the worst stress heal in the game. Was there a reason you removed the stress reduction buff? As is you're better off crit-fishing with the Jester's offense moves if you're out to reduce stress.

Only thing it has going for it is single target focus, which is really only useful if you're trying to undo an affliction. If you're not going to restore the stress reduction may I suggest relaxing the position to let the Jester stress heal from more positions? As is it feels like I'm never using the Tune aside from the end battle 'let it bleed out' turns.
