Either you're the most unlucky player around (every single pug group is a horrible mess), or you're just paranoid and just assume every group is terribad (even if they turn out to be awesome).

Adaptation is one of the key qualities in being an excellent healer.
I love to dps as a WHM, an additional 200~250 DPS in an encounter is nothing to scoff at, but with that being said, if I were unlucky enough to be paired with a terribad group, I'll ADAPT, and switch my priorities over to keeping the group alive.

On the other hand, you should be able to do the same as well!! If you were lucky enough to be paired with an awesome group, instead of being paranoid that the group can suddenly do a 180 and become terribad, why not ADAPT? Start contributing in DPS numbers and make an awesome group even more awesome .
