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

My issues are mostly with the turret deployment being unresponsive, I sometimes have to click the button three times to get the targeting reticle.

Ground targeted skills don't queue, so you can't use them until your previous skill is done. Make a macro that's just /ac "Rook Autoturret" for as many lines as will fit, and it works little more nicely.
