Look, in any game that features any form of "building" your character, this is what will happen:
1)You attempt your first build while getting into the game.
2)You realize you failed because you didn't have a complete understanding of the state of late/endgame and the challenges you'd be facing (or you got lucky with your first build and it sorta works).
3)You respec/reroll your character into one of the handful of optimal builds that either you or someone on the internet have figured out.
Now look at how things go in Diablo 3:
1)You throw together some skill build while getting into the game.
2)You realize your skill build probably isn't suited for Inferno at appropriate MP - possibly even failing out at around Act 3/4 Hell.
3)You respec into one of the handful of optimal builds that either you or someone on the internet have figured out.
It's the same damn process, the only difference is that in D3 you didn't have to sit there clicking a "+" button 300 times.
Stat points are not a real form of character customization. Neither is D2's skill point model. In all cases, there arise a handful of optimal ways to build your character and your only real choice is which of those optimal builds you want to use. It's a result of the game being an ultimately mathematical construction with a relatively inflexible meta-game. There will be things that mathematically work and things that mathematically do not. You either use the optimal build(s) or you accept that you're not performing at peak capacity - there is no ultimate difference between D3's skill builds and D2's skill/stat builds. None. At all.
Does clicking a "+" button somehow make you feel smarter or something? Does copying a stat build from the internet somehow make a character more "yours" than copying a 6-skill+rune build? I just don't understand why this is such a big friggen deal that people are still complaining about it 7 months after the game's release*.
edit: *especially since there are so many actually meaningful things you could be complaining about, like how most of the rune choices are crappy or how every class and build wants the same 4-5 affixes on gear (varying by primary stat only, really) or how even though it'd be an easy fix to make all game areas attractive, we're still running a single circuit through Act 3 or...
