In my experience most people are reluctant to deviate from the rules written in the book, even if these rules go against their preferences. I complained about Exalted, and after one campaign with the second edition rules I basically rewrote all the powers and bunch of other stuff to be more of my liking. I have quite a bit of houserules for my D&D game. But most people don't do this. There are a ton of threads on this forum where people complain about some aspect of the game, but they still refuse to implement houserules or even official optional rules that would fix or alleviate the issue. They want the official rules to be changed to their liking. So yes, official rules is what most people will use, and if the discomfort gets too high, like with 4e, they just abandon the whole game rather than change the game.
