The Breakthrough I'm referring too is regarding the Duality triumphs that increase the drop chance for the Exotic sword. This is a GOLDEN opportunity for future activities. Should bungie remains constant with this, it will give players the incentive to go for more triumphs to get more of a chance to get the exotic while they're completing the seal for that said activity. It's PERFECT bad luck protection. (Assuming if the increased drop chance is not a placebo) Keep evolving on THESE ideas bungie. :)
