The burst comes from precision slash., which is this build should always be used together with master strike.
the basic roatation is the same as a watchman, leap, OS, zealous strike, cauteriuzse, slash, ect.
The difference is that you dont have a short cd big hitter like merc slash. Instead, your burst is more akin to combat burst, coming from precision slash + masterstrike.
That combo needs to be used wisely though, as on kb or stun takes away a huge portion of your damage. try to make sure your target has burned their kb, or isnt looking at you, or that you have full resolve.
