I don't agree that this is a problem. The bosses AoEs are meant to interrupt the momentum of the dps so it's really the mark of good dps to immediately get back into the fight and rebuild their momentum as fast as possible. As such I don't feel it requires any kind of fix.
That being said, the classes always have the potential for new skills being added to help keep the momentum going but I wouldn't expect these until they raise the lvl cap.
Until then, stick with it and I'm sure you'll adjust really soon. :)
