you must play with some really shit people then, I'm usually near the top or at the top on Terminal. Just gotta be quick with your shots and people don't have a chance. I haven't prestiged yet due to the fact I really dont wanna have to get all my perks and unlocks again.
Yeah, I love popping a tatical right on top, near the air conditinor type thing, then snipping people through the giant walkway.
I reached level 70 about a month ago, but I just decided to prestige yesterday.
The AK-47 is by far the best assult rifle in the game. Since I got it, I dominated. Scar-H is also great, I used to to I reached level 70, and i'm using it now at level 25 prestige.
