The interesting thing about D&D rules is that there are a lot of people, at least on the forums, who think that a lot of the rules are great as is and don't like to change them. They'll argue for pages, for example, that the Advantage and Disadvantage rules are great (or that passive ability checks are great). Personally, I think that if WotC had written either of those rules differently, these same people would argue just as passionately that the alternative rule is great. To me, if a rule sucks or you don't like it for some reason, replace or modify it.
