Alternative, Easier Way to bypass the cool down timer

[burners]

) Put ur weapon u are using in your toolbar. (example: Lightsaber)
2) Press the attack u wish to have zero cooldown (example: Powerattack)
3) Now press the attack (Powerattack), Click ur weapon (Lightsaber), And the attack again (Powerattack).

Step 3 can be repeated over and over to keep the cooldown cancelled.
Anyway this is an easier way to bypass the cooldown as u can switch to different attacks easier without macro's interferring.
