While I’m aware that most of the time, in halo 3, equipment was used in solo encounters, I personally always tried to use it to assist teammates in our goals. Trying to hold a point? Bubble shield, or regen. Trying to get the team to an advanced position? Grav lift. Not to mention how these could interact with each other.
In H:I, all equipment except 1 are solo focused. The drop shield is the only team assist equipment, and it’s easily the worst one.
I’m just saying, should they add any equipment to the game going forward, I think some team based equipment would be very beneficial to the sandbox, and promote better team play.
