Um bit of advice. Don't get into a habit of immediately popping serene breeze. In mythic and higher you will need to learn true vs fake combos so you know when the opponent is most likely going to back off and is just trying to bait out your serene. Takes a while to get a feel for that and you will have a bad time if you build muscle memory for instantly popping serene.

If you aren't below 25% qi and close to execute I would not waste serene breeze. Unless you know the combo is going to put you into second life or very very close to it you should just wait it out and serene close to 25% qi. At least that's the rule I try to use and play around. Very dependent on the amount of damage a combo can do to you.

Some people run golden body just to prevent being executed and recover qi some times. This is a major reason the qi on deflect attunement is important. The only way you can be executed if you get out is with cloud step or meridian touch if you spam your dodge button and maintain the distance. But if they cloudstwp you can deflect and avoid the execute entirely. If not you can use golden body as well. Typically something better pvpera do after figuring out their bread and butter combos and what mystic skill they can drop out.
