I've searched here and not founded anything related, so I'll ask:
It's me the only one who would like to have the same HUD settings applied to the whole team?
I like playing without the (too helpful sometimes) HUD, that tells you where everyone is. And some of my friends do like it too but we end playing with different HUD configurations.
Ideally the person who owns the mission should apply the HUD settings to the whole team.
I like to play hardcore but we also mix it with some more light (spray and pray) style. And at some point we all have different settings. Which means one Team mate annihilating all the enemies without the others having time to know what the hell just happened.
This should be something easy to add to new updates...
