This is what I mean. Most of you are incapable of perceiving a game in which kill-count is not, in fact, the ultimate goal. I want to clarify, I'm not saying that tactic/strategy/uber-build games are bad, or even that they're not fun, just that that's one way of playing the game. It's not the ultimate thing to aspire to. "Winning" is not the goal of D&D for a lot of players. Being in-character is the goal. Or living out a particular fantasy hero. Or it's just an elaborate excuse to hang out with your friends, a nerdy version of poker. Now, you can play poker to win money, certainly, but that's not something you do with your friends. If you play with your friends, you play mostly just to play, and if you win money, it's a bonus. A lot, and I mean a lot of gamers play RPGs, just for the fun of it. They don't give a rat's ass about optimising their characters, and their GMs don't give a rat's ass about tossing uber-pumped NPCs at them. In that situation, everyone's happy.
The really important thing, and I say this after about 20 years of playing this game, is not to force a certain style of gaming onto people, but to figure out what kind of game everyone will enjoy. As a DM, if I'm designing a game for tacticians, I try to bring my A-game when it comes to builds and strategies. If I'm designing a game for role-players, then I emphasise story and character. Neither is superior, by which I mean that optimisation is not superior. If it's how you have your fun, then sweet Jebus, do not let me stop you! But don't sit there and tell me that everyone else ought to aspire to the way that you like to play the game.
