If hit points don't represent damage (which I don't believe for a moment) but are just the ability to avoid damage, then why doesn't armor add to the hit point total? I mean, aren't we just using two systems to do the same thing? For that matter, why bother with an attack roll since it really doesn't indicate whether the attack actually hit or not? I've tried to buy the line that hit points aren't damage for years, and I just can't do it anymore. It may not be realistic, but at least it's consistant.
