The problem with "Instant OFF GCD" abilities makes combat feel less rewarding.

I think I'm having the same issue as PLD, when I'm using my normal 3 WS rotation, but I want to throw in a rampart, or fight+flight in the middle, it just doesn't activate until the other GCD WS is finished. is that what this thread is about?

Exactly. Some skills can be used instantly but not trigger a GCD. But all skills must wait until the current GCD is finished before they can be used. This is made more annoying by the fact that that GCD icon animation is not present on these skills, making it appear that they should be usable. At a minimum, the GCD wait icon effect should be placed on all skills/actions that cannot be used.
