"Hidden" GCDs need to GO...

[Faeon]

Go into the settings and turn off as many non-relevant battle effects as possible. Alliance raids and things like hunts are just bad. Hydalen have mercy if someone pops a caster LB while something important is happening!

The lock between most oGCDs is ~1 second though, so recast and error displays really aren't going to help you. In fact, they'd probably hurt you - you'd wait for the timer to finish, then pop the second oGCD, and adding in your reaction time would cause you to frequently clip your GCD.

Viable workaround: Pop the first oGCD, mash the button for the second the moment the first one's icon dims out.

That's why people mash buttons, not press then wait then press then wait etc. Even on controllers, they mash plush Yoshi-P San and his team does the same thing when watching the live letters. I don't know if we will see a change in this, if I had, to be honest, I would so no.
