The issue with a dedication towards both vanilla and mod is that people are always inclined to choose the path of least resistance, leading to the development of only the mod.
When someone raises a problem and the author does not want to cave in, he will just do it in the mod. Thus the mod diverges evermore, vanilla comes to a standstill and people get fed up waiting on a solution that was circumvented by the mod.
Nowadays tons of balancing mods are available, so much so that they destroy each other and their overall purpose
