I picked leech because I expected it would make healing easier and more interesting (walk over blood on field if wounded). I do believe that was the intention. The solution IMO should be to prevent Leech characters from dropping blood, I hope it's not too complicated.
I also agree with the godmode argument, if someone wants godmode more power to them, but I don't want fun abilities taken away from me due to that. Part of the fun is using everything you've got to overcome challenge, when you have to handicap yourself it's just not the same.
