It kind of is though, there are several ways they could tackle this problem, if they even see it as a problem. They could keep healers with only one main DPS spell but if encounters had you healing 80% of the time and DPS 20% suddenly "Glare Glare Glare" isn't as big of an issue. Of course they could also give them more DSP tools, and keep fights as they are, but seems pretty clear that's not something they want to do.
