Ok first you will need to create a new macro, I assume you all can make one of those. In that macro type this:
/Cast "Jin Surge IV" (where the I, II, III IV, is the current level of your skill)
/autoattacktoggle
Next you will need to drag your current level of Jin Surge skill to another hot bar. You won't use this skill it's just so that you can see when the refresh timer has reset as you cant see global or individual skill refresh timers on a macro.
This will allow you to Jin Surge and this use your attack of choice to receive the damage boost vs. auto attack consuming the Jin Surge.
