The first rule is ok with me. As for the second I don't like the DH anyways, which is why I like the National League, "double switches" and substitutions. Fun to see pitcher's who can handle the bat.
Read today why there isn't such a premium on defense in MLB - both SS and 2B "chances" have gone down drastically in the last couple years. So teams are putting their hitters anywhere and taking their chances with the trade-off. Never thought that the "game" that I saw evolving in Little League World Series (all strikeouts and HR) would get to MLB as well. Not sure what moving the mound back 1 foot will do long term. Maybe they'll look at something even more revolutionary such as changing the counts (balls and strikes) to give more baserunners. Time will tell.
