[Help] MW2 Class

[Ironcut]

Hi all! i did the registration 2 minutes ago.
I'm a Mw2 italian player.
So, my first question is: Can you help me with my class?
I use only 5 slot class, all with SoH, SP and steady aim.
the weapons are (i use it because are the first weapon that you can use, and so if i use this weapon i become good with they):
M4A1 olographic
Famas with Hearth sensor
UMP silenced
L86 LSW with grip
Intervention with Thermal scope
Killstreaks: Uav, care package and predator
With these class i have 1.2 Kill/death ratio
But, can you help me to be much stronger?

When playing try to stick around the edges of maps/ like DONT GO IN MIDDLE/CENTER of them. It seriously does a lot because you wouldn't be surrounded from all sides.

I increased my KD by playing war instead of Hardcore.
More players=more chances to kill someone.
I was a mediocre hardcare player and I dominate in war.

my suggestion would be... not to have all of your classes with the same perks!
