NL gets two advantages vs the AL team with Home Field Advantage in the World Series.

I've always liked how the AL and N:L had it's differences with the DH/non-DH rules as a way to "seperate" the leagues. After further thought, the NL needs to adopt the DH to even the playing field for the World Series. The NL won't do this voluntarily of course because they would be loosing their advantage over the AL in the World Series. When a NL team has home field advantage in the World Series, they get an additional advantage because of the non-DH rule. When an AL team plays in the NL park, they are forced to play with one hand tied behind their back. When the NL team plays in the AL park, they get to add an extra hitter to their lineup. Either the NL should adopt the DH or when the play at an AL park, they should still play by their own rules and bat the pitcher. I know that this has been around for a long time, but I think there's enough evidence to show this unfair advantage. I dodn't have the stats on hand, but I know one of you out there can do the research. I would like to see the stats collected pertaining to this argument to see what the stats say abotu this.
