First Rule Of Benidiction:
Use it. If your party is going to die, don't worry about your own death. Chances are, if your party is going to die, you are going to die too, even if you run. So use Benidicition, especially if the Mob is near death. Don't try and "wait it out" to see if your war can get that last Weapon Skill in before the tank eats it. If someone eats it, and you didn't use benidiction, then you could have saved a life. Sometimes this will happen no matter how hard you try (such as a nin who gets hit with goblin rush and a critical hit back to back between utsusemi). But there are LOTS of times where a well placed benidiction could have saved one or two people. 2hrs are there for a reason. If you never use them, whats the point?

Second Rule of Benidiction:
Don't run. If you use Benidiction, there is a chance the mob will come after you. Especially at earlier levels. But it is really important to know that if you run, the mob can still hit you. Players, however, cannot hit the mob while running. So if you run, you will die. And then there is no one to cure the Party. Most PLD have the attitude that they should die first cause they are tank. So if you use benidiction, they will invincible, provoke, flash, cure, etc., to get hate back. If you give your party a chance to get hate, they will, even at low levels. But not if you run.

Double Post Edited:
I wanna add my agreement to the regen thing. In fact, Regen is so nice (Especially at my level with Regen 3) that you can keep an entire party healed without a proper tank sometimes. In my case, I was keeping people alive well enough that my party's red mage started complaining I was leeching XP by not casting real cures. But that, is another rant altogether.
