Defenses are simply at a disadvantage because they need to be able to stop/slow down pure rushing teams, pure passing teams and balanced attacks. SP needs to be spread out all over the place or more salary needs to be spent on specialized defenders to swap around depending on who you are playing. Offenses get to specialize to run specific plays efficiently. Maybe defenders could get a boost after seeing the same play "x" amount of times but majority of success against teams still comes down to Gameplanning. DCs have to do much, much more Gameplanning but if defenses are built properly you can typically slow most teams down enough to out score them. This also assumes that your offensive builds are built as they should be to execute your offensive PB/Tactics.
Bottom line is that the better Gameplan/proper builds win majority of the time. Could defenses get a boost? Sure they could, but there is no telling how much damage this could do to offenses so minor changes would have to be made over time. Once defenses are performing well people will complain about how their offenses are not doing well enough. Just like the NFL, most people want to see their teams put up points. If defenses are shutting owners down consistently some/many may leave GLB out of frustration.
