Very true. In QW unless there was a mission to blow something up then Soldiers were pretty pointless, except maybe for anti vehicle work. All the other classes could still contribute more to the team whether there was a mission available for them or not. I always felt I could be doing more as another class whenever I was a Soldier.
From what we’ve seen of Brink so far it looks like every class and body type is going to be able to contribute equally and being able to hand out ammo makes Soldier automatically an important class to have on your team.
