Because they want to encourage certain procs.

For example, your weapon has 100 impact and 100 slash. Slash procs are better, so maybe you want a -100% impact riven. The result is instead of getting a slash proc half the time, you now get it all of the time, so while the damage from the initial hit is halved the damage over time from the consistent slashes outweighs that in higher content.
