I am not sure if this has ever been suggested.
Would it be possible to list the amount of health that someone has next to their name in the dialogue box in the upper left quadrant of the screen.
It is very hard to read the players name, life score, target and shoot all at the same time. The firefights are very quick and it is may experience that I am only able to process the opponents name. If I am snipering someone then maybe I can take in all of the info but in a general firefight it is lost.
I do notice that I keep track of the other player's relative score. I frequently check the score box to see how many frags an opponent has accumulated or who won a firefight that I heard in the distance.
By seeing the life next to the name in the score box you can go into a fire fight already knowing the relative strength of your opponent. It can embolden you if you know they are wounded and make you more cautious if you are the weaker party.
Thank you for your consideration and I look forward to comments. Have a great day.
