And yet, years of SCA fights of various sorts teaches me UNEQUIVOCALLY that a shield utterly trumps basic armor and even a helmet, which itself completely trumps most basic armor, as general protection from melee attacks. I'm 100% sure Gygax and Arneson were well aware of this, but they wished to encourage and reward the use of armor by fighters, and only mildly penalize thieves by denying them shields, so it was a purely gamist consideration to have a 1AC point shield. All of D&D is like this, the fiction is all bent around a practical and fun set of rules. 4e is no different... Honestly, I think the one and only real objection to 4e, fundamentally, is just that it dared to be a somewhat different D&D. It challenged you all, and the community fell flat on its face. That's how I see it.
