Do MCH's oGCD abilities seem unresponsive to anyone else?

[RichardButte]

Does anyone else feel like MCH's oGCD abilities sometimes just DON'T activate when you press them?

NIN has a ton of oGCD abilities and I've never felt this issue on NIN (even without Huton running). I find myself mashing each one 3-4 times to make sure it ACTUALLY goes off before I move on with my rotation.

I mean that I hit the button, I see the ability's icon flash (indicating that it's been pressed), then I notice a moment later that it hasn't actually gone off.

Am I the only one having this problem?

EDIT: Here's a video of it happening twice: Rapid Fire is pressed but fails to execute at 15 sec, Gauss Round at 30 sec.
