Like a Helms Deep scenario from Lord of the Rings.... That would be freakin sweet. Two sides just standing off. Waiting... And then a random sniper shot is heard and a fallen captain falls dead. All hell breaks loose and the assault on the wall begins.... To commemorate these glorious one time events (clearly we can't have this happening all the time or else we risk boredom and whining) we can have grimoire cards generate and thus capture the battle forged heroes emerging from the chaos! Who had the most kills? Head shots? Grenade kills? Special kills? These heroes would live on forever in Destiny's lore, the Grimoire cards!
