There is a 30sec pause before I actually swing my sword. What stats do I need to improve so that it's not so predictable?

First, it will always be predictable, else... you know.
Second, if you're using a shield, you have more delay than without.
Third, where you noticing this "lag" when duelling, or even when fighting air ?
Fourth, maybe your mouse (computer, overall equipment) is of not-so-good quality and the time the signal "clicking" is sent in game, that many second passed ?
Fifth, maybe it's just a strange feeling, but it's actually as fast as others.
