Once the whole CR Differential is removed, it won't really "matter" what ones CR is, the way it does now. Right? I believe there should most definitely be some difference between those that put in different amounts if effort. Modding your gear, to the fullest, requires more effort than not. Therefore, people should be rewarded with a higher CR number, even if it means nothing more than just that (a higher number). We keep getting farther n farther away from the "progression" that is required in an MMO. Some people ARE better than others (as in life) and it should show. There's no "push" in this game to be better. We can all achieve the exact same everything, with minimal effort. This is one little way to show a small difference between those that do, and those that don't. Even if it actually means nothing (though it kinda does. Better mods = better stats).
