Some of that is so silly to me. Stealth in the cause of good is a last resort?
Sorry, but dedication to the cause isn't supposed to be
easy or
convenient. If you want easy and convenient, go be a thief, or a fighter. Swing a sword and stab people. Sneak around and kill from behind. Anyone can do that. Even filthy goblins can stab someone in the back and take their purse to line their own pocket. That's not what it means to be a Paladin.
It occurs to me that they seem to be coming at their approach to Paladin morality as though it exists in the real world middle ages, where battles involved big formations and standards and knights were expected to fight honorably--without considering the implications of the D&D world with its dragons, mind flayers, beholders, and demons.
No. They understood that what they were asking for was
difficult. They understood that it made things hard. The fact that it was a pain in the tuchus
was the point.
The idea is personal sacrifice
as a source of power. It isn't a sacrifice if it can be done in passing, so you barely notice that you've done it. You don't come by the ability to
smite evil, even where deities cannot go, by taking an easy or convenient road. Your aura of righteousness does not carry the glory to protect you and others, even in the Abyss itself, if you are just some other shlub. The Paladin is the best of the best of the best, sir! And they have to be that best, in word, thought, and deed, every day. Because Evil won't be held at bay by anything less.
(Not that I agree with this as a game design element, mind you. But that's the idea.)
