I am a big believer that house rules need to be documented somewhere so people can see them and refer to them, same as a rulebook. I had so many house rules for 2e, I think it scared off potential players. When I moved to 3e, I just accepted the rules were less crunchy and more for ease of play. I ended up with 2 House Rules, one around Grappling and one on the cost of Regen. Once it was shown to me that grappling was based on Affliction, I reverted to RAW since, while it didn't fit real world grappling, it was consistent. I still double the cost of Regen.
