Yeah, rescuing out of the LB3 animation lock is imo the most common decent usage of the ability now.

Personally I've fat fingered it literally once in a dungeon and promptly apologised for it, outside of getting pulled through the middle in Suzaku it's really not that big a deal and outside of friends trolling each other to make farms more fun, I rarely see it getting abused. IMHO you're much more likely to get cleaved because of an oblivious/troll tank than you are get rescued and actually killed because of it.

And frankly, in 99% of content, who even cares if you do get killed, is that that big of a deal? Go look up the sort of clean up operations that used to be required to recover an old Everquest Planes or Vex Thal wipe. That's a death that's a big deal. FFXIV's 'death penalty' is an absolute joke by comparison. A bit like this thread.
