I.. am not that sure how this is really useful though if there is nothing you can do about your teammates health...
- Knowing who should lead the party when a group of you is traveling around the map. Usually when some guy took some damage, I'm courteous and try to stay ahead of him to take the first hit of whatever comes our way, and it's hard when you don't know if they're at 2hp or 100.
- Generally, knowing what kind of shape your group is in.
- Knowing who to protect with your bullets or body when they're retreating
And finally...
- Makes it easier to FF jerks/n00bs down to as little hp as possible without killing them.
