How scared should I be about DPS?

[Elamys]

I mean, your main role is healing. You should be focusing on healing first and foremost. If the group is taking a lot of damage you shouldn't be flinging Malefic. DPS is something you do when the healing required is light or nonexistent. If an Aspected Benefic keeps the tank alive, throw that on him and do some damage in the meantime.

Don't be too scared about DPS. Most people are more relaxed about it and don't expect you to output top DPS numbers all the time. It's a lot easier now that Cleric Stance is no longer a thing. With practice you'll come to find more windows you can DPS in. Even something as simple as throwing out a few Combusts helps. And sure, there may come a time when someone dies because you got a little too focused on damage, it happens, but so can any other kind of mistake. A simple "my bad" is enough.
