This may also be an important information for MM or SV spec hunter using hand-weave 1:1.5 shot rotation. The three hot key [Steady Shot][Multi Shot][Arcane Shot] for hand-weave 1:1.5 shot rotation should be replaced by the three hot key [!Auto Shot/Steady Shot Macro][Multi Shot][Arcane Shot] to reduce the chance of Auto Shot clipping by the GCD mechanism.
