It works perfectly in training mode where friendly bots with full health will not show the bar and bots taking damage will show the bar. But in PvP it’s broken. It will show the health bar for everybody and after some minutes of play it will hide it. It’s either Default or Off.
So apparently it never worked as intended and I’ve seen some posts that mention it for everybody.
I really need this feature to be fixed because I’m wasting time trying to decypherate the health bars.
Here is a topic that is more accurate about it: Allied Health Bars - Contextual Option Bug
Thank you.
