I think it be really cool if Salted gave the mitigation and healing it does from PVP. The damage boost is probably a bit much, but the other two would be really appreciated, especially if its mitigation/healing affected the entire party.
It would make it an interesting tool thats a mix of damage and defensive utility, could also change Salt and Darkness to give a burst of healing while inside it as well.

I really hope the skill isn't scrapped because honestly 6.0 PVP has shown how cool Salted Earth could be as a skill.
