Differentiate pure heals and shields?

[GrimGale]

Question: Isn't the differentiation being Regen x Shield, instead of Pure heals x shields?

That was the impression I got... "basic" heals would be for everyone, but part of the healers focusing on regen effects to supplement that and the other on shields.

I think Yoshi P calls "Regen" healers just Pure Healers.
