A huge factor in reticle design is the application of the optic, especially at what magnification the user will most likely be on when employing the optic. With marked 10 mils of drop below the center crosshair (with a 100 meter zero), you can account for drop out past 800 meters if shooting heavyweight bullets out of a 16" 5.56 gun. However, it will be a pain in the ass to consistently hold for wind unless you have some kind of reference, as with the Horus reticles or the type that a0 drew up. Really, for work past 300, it pays to dial.
There are a lot of ways to work with/around different reticles, a discussion of which would be a pretty significant hijack/derail. I'm, not saying that anyone is wrong for wanting a certain type of reticle, just that there are a lot of factors and techniques out there that are best understood by use.
