How is nightsister acolyte a healer?

Agreed on the Lumi thing. She's been needing a healer tag all along. She hits kinda hard, for a jedi...at lower levels when you haven't got that many toons yet. But if she's your dps at higher levels, you're gonna be in trouble. She's actually my main healer for gw, when I need one.
Acolyte is a toon I haven't unlocked. I have some accidental shards, like halfway to unlock, but none that I've actively farmed. I'm not all that familiar with her kit. At higher levels, do her abilities heal others? I never would have noticed the healer tag if not for playing around with the new sorting feature.
