Buy Premium so you can get all of the DLC!GREAT!! downloading DLC now!
Yes! either a 24/7 Operation Metro, or i have found that 64 player Domination on Locker or Metro work quite well.Buy Premium so you can get all of the DLC!
On-topic though, whenever I use my XP boosts, I always try to find a 24/7 Operation Metro Conquest Server. You can literally fly through the ranks and get a lot of unlocks. Not to mention, if you get 10 kills with an Assault rifle on this map along with two assist medals (or trophies), you unlock the F2000.
Not going to lie, when I play there for the purpose of ranking up, I always use an LMG. I've mostly been using the AWS. Sometimes though, I'll play there just so I can unlock attachments for a certain weapon that I like.64 man conquest, 300% XP boost, and LMG with bipod = major leveling up haha.
