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.
Most people don't do that because they don't have knowledge, time or will to do it. They just pick up the game and play it as is. At most, they ignore rules they don't like if they can do it without breaking core mechanics of the game. Some people like to tinker and DIY stuff. Some just like to buy and use.
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.
Complaining and not doing anything to solve problems is national sport where i'm from. Bitching about something is easy. Doing something to fix it is hard. And people tend to be like electricity- follow the path of least resistance.
Although, if you need to do serious rework of good portion of basic game mechanic, maybe it's not best choice for you. Lots of times it's just more time efficient to just pick up another game that matches your play style better out of box. Problem is, sometimes there aren't enough people in your area that want to switch to something else.
