Sme feral dps math that I find interesting, but probably no one else cares
As cats, we want to generate 5 combo points by pressing only 3 abilities as reliably as possible. For simplicity, I'll refer to this as "The FiveThree".
The higher your crit chance, the higher the chances that you will do that. But exactly what is the correlation? Here is a graph that shows it: https://www.desmos.com/calculator/iryz7k9hdk
You can click that graph on the X-value that correlates to your current crit chance and the Y-value will show your odds of getting the FiveThree.
If you have 50% crit chance, your chance of getting the FiveThree is exactly 50%.
If you have 75% crit, your FiveThree chance is 84.375%.
Increasing your crit from 49 to 50% increases your FiveThree odds by 1.5%.
Increasing your crit from 74 to 75% only increases your FiveThree chance by 1.14%.
In conclusion, I doubt anyone likes math enough to care about this information or to consider it when deciding how much agility to gem. But I found it interesting, so maybe there's a chance that someone else would too.
