Except the circle doesn't ever break, per se. People can join or leave as they want, but there will only be an effect as long as two or more healers are radiating. If a healer burns out, then they drop out of the circle. It wouldn't affect any other healers in my incarnation (although maybe it should). As Xavius said, this skill is remarkably strong. It should be expensive. Healers would be standing back from the main group, so arguably in a safe position anyway.

I would really like to see this looked at, so I'm bumping it. Bump, no bump back.

Once again, bumping. Admins, feed back would be nice if you would please.

Healing is very useful as is. If you want admin feedback on an idea like this, forwarding it to your envoy is probably the best idea, even though the feedback might be limited to a 'No".
