Are you pre-casting heals or are you casting after the tank gets hit? Are you pre-casting Embrace? If the answer is yes to pre-casting, then you're fine.

Remember, my HPS can be 200 higher than yours but I can be failing more because my heals are being front-loaded, I'm overhealing excessively and I'm being too reactive and the tank is dying when they eat a crit on a hard skill.
