As far as my memory recalled, he sold SGE as "The healer that heals by attacking" & "-able to augment its own capabilities" rather than -the- DPS healer but I could be misremembering at this point or simply paraphrasing. But assuming that was what he said, they have failed to checkmark their own bullet points regardless.

By its core design - like ASkellington mentioned; we're going to do both. They need to acknowledge this and actually give more than just cookie crumbs to their damage options.
