well, there ARE uses for it (no thats not me, just a video i once found)

but yeah, some days ago had a bad group in A1, almost wiped on a rocket fail, the other healer raized me instead of LB3 for some reason, i went LB3..... and got laser in my face from both bosses while in the animation lock afterward, rip me >_< (we wiped soon after anyway)
this animationlock could at least be a bit shorter, its stupid to jut stand there for like 10 seconds
