Not going to lie, this almost hurts to see. Just like the current destiny, the best screens always seem to be the ones that we're not involved in. Kind of makes me think of destiny as an rpg with the roles reversed: despite everything we've done, they're the main characters, and we're the solder npc's. We're basicly the city guards that you see in most rpg type games, or more accurately those mid to late game brotherhood guys that you see being dropped off to shoot bad guys from time to time while the real characters continue their adventure. We even operate in teams made up of the same three basic combat roles: a big, bulky tank man, a moderately armored scout, and a scribe sent out to collect knowledge. Despite this display of combat and npc character involvement in the trailer, destiny's character interaction up this point hasn't given a reason to hope you'll fight along side them or even see them in combat during a mission. We'll more than likely have them talk to us on radio until the battle/mission is over or have another cutsceen of a main character jumping in to save us from two or three enemies. That's if it doesn't skip over us entirely for a cutsceen of the npc's planning the next move. That's not what I want to happen, but what will likely happen based on what we've seen over the past few years. But if an npc like Hoffman can unexpectedly join you in the fight to protect humanity's only unsinkable and last fortified large-scale city for a comfortably decent portion of a level in Gears 2, I see no reason why you can't have at least one of the three vanguard npc's join you while you're supposed to be fighting in the last city on Earth.
