Just an FYI, I petitioned to a GM about this that the matching armors to this set has been removed from the game. You used to be able to aquire the parts from the quest lines in the zone. But now they replaced the quest rewards with "Outrider's", like they did in the previous zones, all with a shiney metal chain appearance.
I petitioned to at least put the matching set all on the faction merchant so they are at least obtainable.
If it isn't still by the time you read this, I would strongly suggest /petition'ing or /feedback about this merchant to sell the complete set of Daredevil Armors.
