Exotic gear will drop in old content.

Sort of pleased to hear this even if i was hoping to leave the vault of glass behind in search of newer missions to play. Literally all i need from VOG is the machine gun and both fusion rifles. Everything else can get lost as i already have the VOG hand cannon which is currently the best in the game + the shotgun and sniper and the rocket launcher which is also excellent.

In terms of Crota Normal, i'm done with that as i own every weapon and Warlock armor piece from that piece of content. The only thing i need is Armor for other characters which i'll get in summer. From Crota hard, I just need the crux to upgrade my auto rifle to exotic quality and the hand cannon, then i'm done.

So, yeah. Good news, but won't bother me much.
