So which of those 2 challenges do you like better when ranking up weapons?.
It baffles me sometimes. I've been ranking up the swat and while working on headshots didnt do so well until I put select fire on it. What a beast!
Anyhow ........ I was working on the no attachments perk tonight on it and over the course of about 6 matches got 4 bloodthirsties and a buttload of kills ......... finished the 150 kills, switched to my no perk class with rds/sf/fmj and got my *ss handed to me.
It seems that way with just about every weapon. Whatever I think will be easier and harder are usually backward to what I predict using normal mixed classes with it.
