I use it, but I'm not really happy about the skill.

Mainly I think (as a compromise to both sides) it should be kept as is, but with movements not cancelling cast times. (So cast times still exist, but you can move while casting). Would still keep the uniqueness and desired mobility of the class, while still having the cast time with damage benefit/detriment.
But I digress.

For instance runs I keep it up 99% of the time. I'm still working my way through the end-game post MSQ content and EX's. So far the only thing I've actively kept it off for was trying to learn Titan EX. Because Titan. -shudder-

When I was leveling/killing something solo, then I tend to keep it off because I like to kite what I'm killing. I just find it fun, and since I'm doing it solo, who the heck cares how I kill my target?

It's still pretty essential though. And if I'm doing a dng run with another bard who's not using it, I usually give them a silent side-eye.
