At least in the World Series the home team's league rules apply. I like it to stay the way it is, so that the AL pitchers still need batting practice. No doubt the pitching schedule for the Series has a lot to do with how well the AL pitchers can hit, so the bad ones pitch at home where it doesn't matter.

I'd prefer to see a return to the old era, when pitchers were noteworthy hitters also (Babe Ruth is the perfect example). If also prefer to see less emphasis on Relief pitchers and a return to pitchers going full games like Nolan Ryan. But those times are gone. With the current pussified league, you may as well allow DH for NL, since modern games have devolved to the point that players are pampered millionaires who are so specialized in their role and delicate that sneezing can cause an ACL injury

I actually prefer no DH. It really forces some crazy strategy-pulling pitchers early, double switches.
