Here's what I believe:
1. There isn't really a right or wrong answer on the whole "heal out of town" thing. There are preferences. I'm looking at this whole argument and it's about as silly to me as one person claiming the provable superiority of chocolate ice cream versus someone claiming the provable superiority of pistachio ice cream.
2. Games should be made to accommodate the various preferences out there. There should be someone who makes chocolate ice cream, and someone who makes vanilla. It would really suck if every game was made according to the same set of preferences, and no one could find a game which catered to their "eccentricities."
3. I like me some pistachio ice cream. I also like it when there's no automatic healing in my RPGs.
