Eh wanna ask if is there any regular LYN member MW2 matches on daily basis?

I just started playing yesterday (damn those business trips!) and my first impression is the all the maps looks like a camping haven! Cant do the regular run and gun thing anymore unlike in KZ2...

Now working on my LMG thats the closest gun i can find next to KZ2 standard gun. Any advice on the best perk combo for LMG?
