I've had problems with staggering wind element. (Cyclone and Jinpu)

Pantagruel is my 1st case. Had to kill one w/o stagger because of it. The next one was wind as well, i had to try multiply times to stagger it but finally got it to land.

Treble Noctules is my 2nd time in 2 days i've had this problem. I staggered Treble Noctules but after multiply tries.

I've only had this problem on wind. (Cyclone and Jinpu)
These are probably the only 3 times i've had to wind stagger in the last couple days.

fyi : i know how to red stagger NMs. I wouldn't post this if the stagger was possibly badly timed.
