In the vein of min-maxing soak and wound threshold, it seems that healing is one powerful skill as well. By healing, I mean the medical skill
The resident healer in our group has 3 proficiency dice and 2 ability dice.
Add to that, that "an encounter" is not very well defined, and he is able to make almost unlimited medical checks, keeping everyone in tip-top shape at all times.
It has come to making med. checks just to try to cure 1 or 2 strain.
I thought about house-ruling that you can only make a med. check per character once every 24 hours, but that also seems harsh.
It kind of takes the challenge out of the game, when the entire group is untouchable.
Any suggestions?
