What materials are required to craft a full set of exotic armour?

I want to make a full set of exotic "medium" (ie: leatherworking) armour but haven't bought any of the recipes for the insignias yet. In this instance I'm wanting the Precision and Condition Damage stats on my gear so I'm probably going to go with Rampager's Insignias.

Before I set out farming for materials, how many of each material will I need to craft a full set of exotic armour?
