The fact that all these house rules are not the same for everyone simply proves my point. How many house rules did you have in 1ed and how many were answering the same problems as the table next to you? In my case, the shared house rules were 5 pages long, and these were at about 12 or so different tables. All these rules were "needed" to have a consistent gaming experience across all tables as many players were going from one table to the others. Some rules (initiative and surprises in cases of duergar and rangers...) were even given pre-tournament simply because there were so many ways to "correct" the problem...
Most house rules in 5ed are for "preferences" and not for "conveniences and necessities" as was the case for 1ed. But don't you dare say anything against 1ed.
