So, looking at it.

Sage heals via DPS, honestly, I can be down for that. Sure, sounds cool. But it can be a double edged sword in that you may use other healing abilities less, so the variety still needs to be there.
I see 6 moves that contribute to DPS with only 1 on a long recast. This is positive, though I am curious how they'll work together and I'm hoping we don't get relegated to Dosis spams.
Healing looks like it has some tactical elements, which I approve of. Even if this is a part of SCH's identity.
Shield healing? My feeling here is that it's not going to get much dependence on its shield healing and I feel like it's only going to be a shield healer in name and not practice. This is where I feel like it's going to trip up and makes me concerned this "Pure" and "Shield" healer distinction isn't going to work out.
