I don't like house rules that supposedly "fix" something, what's broken in DnD is often just someone's opinion and I often don't agree with it. However, if they announce it differently such as "My table and I don't like the way this thing works in DnD and this is what we did to change it" then I'm often more likely to respond positively, the same with house rules to people create to get a certain feel for the game. I have some house rules, sometimes just to see how something works out and whether it makes the game more fun (I guess ultimately, more fun is what all of my houserules are about).
