Tossing an aero here and there

[Ghishlain]

The amount of DPS time you get as a healer is dependent on how comfortable you are with your skill and equipment as well as the skill / gear level of your party. Bear in mind that healer DPS is lackluster without Cleric's Stance and that upon activating Cleric's Stance, you won't be able to turn it off for five seconds (two global cooldowns). Additionally, Cleric's Stance likes to "stick", in the sense that it's hard to turn off and sometimes the button feels unresponsive. But clicking it too often may turn it off then turn it back on immediately, thus screwing you as well. There's a bit of nuances to Stance dancing that takes some time to practice and learn.

However, Stance Dancing and DPSing is one of the most common ways to reduce healer idle time in over geared situations. For some people, the amount of idle time hampers the enjoyment so they enjoy pushing the class to the limit, while other are perfectly happy completing their role as a healer. Make decisions based on your comfort level and play style

You won't have the acc to reliably stick every Aero.

This generalization is false. Healers have perfect accuracy in all content outside of Coil (where your focus should be more about heals than DPS while you get comfortable with the content).
