Here's the problem. The AL wins the game and people say that they're the dominant league so they should have home field in the World Series, and all is right with the "This One Counts"(tm) format. But what if Hoffman got the final out and the NL held on? Then the same people would be crying that the AL is still the better league, and that the same trademarked format was bogus.
It comes down to this. The sample size is too small. Home field should be determined on one of two factors before the Midsummer Classic ever gets involved.
1) Best record. Win the most games, play the most post season games at home. What's so hard about this?
2) Interleague Play. Much more significant sample size than just the All-Star game.
