However, during those three seconds the boss could probably have hit you twice, which means you'll have to spend chi on Purifying Brew, which means another GCD lost to create another chi used for PB.
Who knows, you could have been lucky and the boss never laid a finger on you during those 3 seconds, but you could have also been unlucky and had the boss hit you with two nasty hits during those three seconds.
