@epwna Ya know what... my understanding was that it was better to focus cap rather than use Aimed Shot on a target without Vulnerability on it. I double checked Icy Veins and hit up the Trueshot Lodge Discord, and it seems I was wrong (because Sidewinders is just around the corner and gives you 50 Focus).
One thing that's important to note is that the hard cap of Focus with Patient Sniper is 150, not 120. So the soft cap should be ~110 instead of 80. 80-90 focus is a pretty good number.
Regardless, even a simple "here's the number of Aimed Shots casts (i.e. excluding artifact procs) that hit vulnerable targets vs the number of casts that hit targets that weren't" would be helpful. This way, in my efforts to help other Hunters, I can look and say, "Ok, we both cast 60 Aimed Shots, but I had 13 more on Vulnerable targets... either he has insane bad luck, or he's doing something wrong."
Also, Marked Shot should for sure always hit a Vulnerable target, so calling out any that didn't would be nice, too.
