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

Added a video of it happening twice to the OP.

Rapid Fire is pressed but fails to execute at 15 sec, Gauss Round at 30 sec:

You're hitting your oGCDs before the previous animation lock is done, so they don't go off. Pay attention to the timing. You can only hit 2 oGCDs max between your GCDs and only one during Rapid Fire. All abilities have variable lengths of animation lock that prevents using other abilities at the same time. It also depends on your latency how fast the server registers that you've hit an ability so your mileage may vary.

I find that the buttons aren't responsive enough to fit into the tiny wildfire window, it can get a little stressful trying to get everything off in 10 seconds.

I definitely think they could afford to extend wildfire and overheat duration to 15-20 seconds. It would relieve some of that stress and bring mchs damage up a bit.

Long WF is extremely clunky to maximize on because sometimes it doesn't fit into fight phases at all and becomes literally a wasted ability when it doesn't have time to explode. I prefer the shorter window.
