What kind of game where you playing?
At1d6 per 10 feet fallen, what 9d10 hit point fighter could survive a fall from orbit? And wasn't falling damage originally exponential? Ie, 1d6 for 10 feet, 2d6 for then next ten for a total of 3d6 for 20 feet?
200,000 arrows = 1,000 hits on average, assuming you'd need a 20 to hit. What AD&D character can take 1,000 d6 damage?
And an armorless character in a medieval period is quite stupid, as he will be destroyed by the guy in armor, so I think it models it quiite well. Try picking up a stick and hitting your buddy dressed in full football pads and helmet, while he does the same to you while you wear jeans and a t-shirt. Sure, you might get lucky and bop him in the knee, but he can hurt you by hitting you ANYWHERE. And plate mail even had substabtial coverage of joints, weaker coverage, maybe, but better than nothing. You can always play an unarmored fighter, though, as long as he's an archer.
I'm no expert on medieval warfare by any means, but c'mon, what kid hasn't had backyard fights with wiffle ball bats and football helmets? Garbage can lids make excellent shields, btw.
