It's not perfect but I think it's the best way to compare what a player did in their era compared to the rest of the competition. That isn't to say that an ERA+ of 127 is the same in 1910 as it was in 1975 or 2007. Just like WAR, to me it's an attempt to explain performance. It isn't the end all though.
Deacon White's OPS+ of 127 at least tells us he was a dominant player compared to the rest of the players in his area. It's especially great for a catcher.
