Victoria Rules
There has to be enough of a defined out-of-the-box framework to allow a playable game without any DM modifications or input; mostly for those who are either new to the game or who just want to drop the puck and play.1. It's WOTC doing the defining. You said it yourself, you don't like WOTC defining the rogue. What happens to those who don't like how a class is defined?
2. It's WOTC telling everyone how the game should be played. Yeah, we've seen how well that goes over.
This is where WotC have to be very careful, and very clear, to note that all contents in the books are to be treated as guidelines, and may be modified by the DM at her pleasure and convenience. They also need to make it abundantly clear that it is the DM's inalienable right to do so.3. It disempowers DM's. Players will possibly demand default options be available. After all, they're default for a reason aren't they? So, why are you messing with the defaults?
Not necessarily. In 1e numerous adventure modules went outside the box, with the changes (new monsters, spells, sometimes abilities, etc.) explained in an appendix. Then again, 1e didn't have quite the splat disease later editions wound up with.4. It forces game designers to conform to those defaults. You can't start dropping supplements and modules outside the defaults without causing all sorts of problems with marketing and whatnot.
They can be special snowflakes if they like.5. It simply adds fuel to the fire of DM's who insist that any player who wants to be, in your words, "a special snowflake" is a self-entitled, whiney git.
At someone else's table.
