As it is, for any Champion to fight a dozen men... unless the dozen men just really suck, well. It's unrealistic. I doubt that happens much in real life and that concept has just been popularized by Hollywood. Everything should have a counter. A counter that isn't "do the exact same thing but better".
Realistic?! Man, have you ever read a fantasy novel in your life? The ability of a hero, or anti-hero, or antagonist, to defeat large number of inferior foes is a central aspect of much of the fantasy genre. Have you ever read or seen Lord of the Rings? Aragorn wasn't magical. Neither was Gimli, or Boromir. Or really even Legolas (besides a few bits and pieces of magic here and there, but largely his strength came from his training and his elven heritage). The carnage those characters inflict in the movies is not really a departure from the books. Their training, the status as the heroes of the story enabled them to face and defeat overwhelming numbers over and over. Brad keeps telling us that the adventurers that we can recruit as our heroes are the pesky adventurers you play in D&D like games, the characters in fantasy novels that stir things up in the kingdoms, while we are the sovereigns governing those kingdoms.
Realistic in this world? No. Realistic in the vast majority of fantasy worlds? Hell yes.
However... all in all this is really caused by instigating a hard-limit in armies. It makes the quality versus quantity argument weaker and it's very much bleh. Allowing champions to not be included helps but... I don't like it. If you remove that limit, s'long as I have a 5% chance to kill a super unit, I can throw enough mundane units at it until it dies.
Couldn't have said it better myself. And like I said before, how can Dragons be the overwhelming powerhouses that he wants them to be if we can't actually swarm them with huge numbers? Without the ability to pit quantity vs. someone else's quality, quality will always win and the person with the Dragon will be undefeatable unless by someone else with a Dragon.
Very good post, there isn't a single thing in there that I don't agree with wholeheartedly!
