Not a fan for a few reasons.

I don't think ranking needs to be made less risky.
If this happened, I'd want to increase con-loss to mob-deaths so that there's even more punishment for throwing yourself at a mob over and over.

Risk has rewards and, well, risks. I don't think the current loss is too much of a penalty.

This is just my opinion, not speaking for the rest of the staff who can post their own thoughts .

Edited to add: Something I would mind LESS is further incentive to group, compared to this.
