1: it's something to do during content droughts (like this summer) 2: as a collector it's nice to have them all 3: those spawn animations are very cool IMO 4: get all 3 on each character and you can then have a faction cloak on, no matter what faction you're working with 5: I'd much rather have all 9 faction items and 200 resources left than not have any faction exotics and just have 1000s of coins and motes (if I have the resources, I might as well use them)
