I mean I could put this to the test on lilith or something, with tens if not hundreds of thousands of attack rounds trying to cap TH before kills if anyone thinks the effort of tracking crit hits would be worthwhile but I am entirely content with just leaving on TH gear when farming anything. I can check on it. I just feel like it's a very unlikely outcome that crit hits improve proc rate. I think that idea maybe comes from SA procs which are always crits.
