When the Resistance DLC came out they made it a lot easier to get the Volk through challenges, that has ended now so the only way of getting it is through collections which takes ages to build up your armoury credits unless you're lucky in opening packages.
I don't have a problem with the recticles really, I use the iron sites on all the guns which is rare for me.
Question about challenges, I went into this weird mode where you walk around a campsite where people are wandering around like a MMORPG and one guy behind a desk offered me some challenges, one was to collect 20 kill confirmed tags, so I did it and it increased a value by 50 of something, like a little icon of a person and a plus, any idea what it is for? Was rather hoping i'd get a gun or currency for a gun
