I think the only way to have access to that new vanguard armour is to beat the VOG on hard. That would make it to where the people would have to level up high enough to do the raid. I think that should also apply for when the next expansion comes out and the new raid begins. This would make it as difficult for the new player as it was for us when we first started. I have yet to beat the VOG on hard because I never have a team that works together and I have new boots but if Bungie implemented this rule to the game I would, without a doubt give up my boots and level and try to unlock them.
