This is just a kind of reminder, as this is a quite old bug, but it's still working and many people may not know about it.
Simple bug, it allows you to keep your fear ward at all times (perma immune to fear, unless you get unlucky).
The trick is the following:
When you are about to get feared (you see a warlock casting a fear on you, or you know that this priest is going to mash his psychic scream button, etc), just sit down (X by default I think, just check your keybindings).
When a fear lands on you when you are in a seated position (or in the process of sitting down), your fear ward will not get consumed. You can do this as many times as you want, until you get caught offguard and get feared while not sitting down.![]()
