I usually try to DPS while healing, but my first and foremost concern is keeping peoples' health up. The only time I'm deadset on getting my DoTs and such up is right at the pull - where I hopefully have an Adlo and Stoneskin on the tank to cover for me while I do it.
That's not to say I haven't forgotten to heal while DPSing. I was in one of the new level 60 dungeons and the tank dropped because I was trying to help DPS the adds. I could defend myself by stating that our DRG was tunneling and I felt I needed to cover for him... but I really wasn't sticking to the role I'm there for. Helping DPS is a bonus to help mitigate future healing (by making things die sooner), but it really wasn't what I was supposed to be doing.
Then again, it's hard to tell when you can DPS and when you can't sometimes - especially with PuGs. You never know when a DPS or tank is going to space and get hit by a big attack, or ignore other mechanics like adds or "you have to click this thing to live" stuff. My first fight with Bismarck, I was literally doing both the shields and one of the spear-guns because people were ignoring them. But that's another story entirely.
Your job as a healer is to heal - and being able to add to DPS should be secondary. So, the idea that AST might not be able to add enough DPS themselves doesn't bother me (unless I'm soloing). They can keep people up, and their cards either aid in that or - when put on the right people - boost their damage to make up for it (either through straight damage boost or skillspeed increase). I get a feeling that putting 10% more damage on that Monk goes a long way to mitigating the AST's own DPS capability.
