10: The Glasshouse
The existence of a Year Two Glasshouse in Destiny would actually make a lot of current TTK fights just a little bit easier. For example, having that extra bit of time with Weapons/Blessing of Light during the Golgoroth fight would be much appreciated. You wouldn’t have to worry about going back and grabbing another refresh, just keep those Touch of Malice hits coming. Pretty much any instance where you run out of a Defender’s bubble perk and have to go back, could be a time where it would be nice to have The Glasshouse back.
