If that's going to be the case, though, the oGCD abilities need to temporarily go dark until we can use them again.

The entire purpose of a GCD indicator is so that we know that pressing a button will not activate the ability at that time. Also, pressing a GCD ability while the GCD is still counting down will give us an error message and sound so we know that the last button we pressed did not activate the ability.

This cannot possibly be working as intended. Either buttons that are lit up and look pressable (especially those that flash as though they've BEEN pressed) need to actually activate the corresponding ability when pressed, or we need some form of "animation lock" indicator, similar to the current GCD spinner, that lets us know when pressing a button won't do anything.

Also, I posted a video of it happening twice in slow motion in the OP.
