I just wanted to point out (in a very non-confrontational way) that the fact that SO MANY people think this means there has to be some truth to it. Tons of people would not have spontaneously come to the same conclusion by coincidence.
I've been both a Diablo and WoW player, and a huge fan of Blizzard games (they really do strive for quality), and the entire concept of 'builds' comes from VIDEO GAMES. WotC uses this very term now to describe their preset 'character paths'. Just as in an video game - be it online or console - if you go off the beaten path and do not follow a pre-established 'build', then your character is considered inherently weaker to everyone else.
Now, I'm not going to defend the truth of that statement - I have created at least three characters that can whup anyone's butt with builds that people said were 'wrong' (and one of which went onto to become one the favorite builds after I stopped playing WoW). I think the whole concept of uber-powerful builds destroys the element of individualism, and I strive for uniqueness in every character I create... even if it means giving up a little power. Sometimes, the element of surprise (when you do something completely unexpected) out-weighs the power-loss.
Anyhow, I digress - I just wanted to say as both a long-time video gamer AND PnP gamer, I do notice that D&D has acquired some very VGish mechanics of late. I'm not going to say weather that's a good or bad thing - that's a matter of opinion and is decided by each person's personal tastes. I have heard that combats have become easier to run (so long as you buy the pre-prescribed miniatures from Hasbro), so if your group is combat-heavy then that would probably be the appropriate choice for your group. Combat to me is secondary to storyline, so the rules matter very little to me (and I have used MANY in all my years of GMing). If I didn't already have a plethora of unread/un-used 3e/OGL material laying around, I might have gone that way myself.
