When hovering your crosshair over a teammate (to display their name), it should also display the teammate's health, in either number form or as a health bar.
It wouldn't be difficult to add, and it would make teamwork much easier. You could:
- Know when to protect weaker teammates
- As aliens, know when your allies have regenerated their hp, to resume the attack
- Just to know your teammates' hp in general
I just figure that it's easy to add, and would help encourage teamwork a bit.
