To the OP: Problem Solved. Good job.

Now then, to those who aren't fickle, or are capable of embracing change, are you aware that:
1. You can move within the last .30 seconds of your cast and not be interrupted.
2. Since Bloodletter is still instant, you can already begin casting your next action on top of its animation.
3. For movement/positioning heavy phases of fights, you can freely go in and out of Minuet/Gauss and not lose any DPS uptime on the target enemy. (Consider also the fact that BLMs and melees still CAN'T do this.)

There's no need to "Git Gud" if you already were. Stay strong, play songs, and Bard hard, true bowmen.
