one small idea if you did not want fall dmg as a gameplay mechanic, you could with the fall down to the medkit, maybe just have one of those fire emitters that was on E2M3 in that fall down, so that way the hurt is from something that is not the fall its self, so a short fall passing through the flame = get hit, then heal with the med kit, maybe that way would be better, if you did not want to implement fall dmg as a gameplay mechanic.
it would encourage a risk = reward that you are going for, plus you could have some fun with the idea that it is a incinerator/cremator for the hallow's disposal or something of the sort and land on a ash pile.
