Okay, so look at the proc please. It only affects targets level 95 and below, and if the target is level 103 or higher, the proc resists more likely. So what's the logic behind that? Why does the resistability increase at levels where it doesn't even affect the target anymore? And why is there even a level restriction to those procs? This is just utter rubbish, and almost every crowd control proc gets handeled that way. I just don't get it.
And by the way, Fabled level 80 item procs only affect targets level 90 and below, 5 level less than Legendary.
