Just because you have higher numbers doesn't mean you have any idea on what your % is. You can add your stats and know that you have capped acc? Too much acc for a given fight? Not enough? Once players find out the specific of mob stats that can be possible, but until then you'll need some form of tool to get the specifics.

You're one of those players who just thinks "bigg numbors gud!" and call it a day, aren't you? I'm sorry, but blindly adding stats for the biggest number possible is NOT always the best way to go. As a general rule of thumb, yeah it's going to be better. But at some point you cap, and at some point those stats are wasted on something that would overall be more beneficial.
