I know levels do not mean alot. But alot of us have 1st, 2nd, 3rd, or even 4th accounts. And I am sure you have each have had a GT that you made with a trial or something.
So at what level do you actually
have to try? For me, I noticed with Team Slayer and Team Snipers from the past couple of nights, it seems to be at or just above level 20. That doesn't mean that it's hard, just that I can't just walk around and get kills. Between levels 10 - 20, I usually can just walk around and they just seem to drop dead around me.
Now these aren't that great, but you get the point. . . . . . . . .
Rumble Pit. 1 of my worst maps. Off host. SMG only. 25-9
I get called a modder. :/ 26-7
I was the only one not in the garage the entire time.
All I hear is, "****in modder!" :/
21-9 and I still lose. 
My back hurts.
And I actually had to start thinking in this game.
I choked on the killtac.
Now don't flame me. This isn't me showing off how uber badass I am. But I seemed to notice that around the rank of 20 in everything, I actually have to start trying.
What about you?
