I will make this quick and easy... If Eris Morn is there to "help" with Crota...right? Why doesn't the gear she gives you (the arm pieces for completing the urn of sacrifice) have an Anti-Hive perk on them? Whats an "Anti-Hive" perk you ask? Hive Disruption like on the weapons, or Extra Agility, Extra Damage to Over Soul, you know...that stuff. She appeared with the DLC1 Crota stuff so why not have her give the guardians gear that helps with the Crota raid or at least against the hive. I know this maybe a little late in the game to say this...but come on, it's never to late to teach an old dog new tricks :D
