As I'm starting to care less about my score, I'm trying out some new weapons.
After watching a few montages online I've tried my hand at some quick sniping, and it's crazy frustrating, I don't know how those guys do it so consistently. Granted, montages are no proof of that, but I subscribe to a channel on youtube where the guy does. Every once in a while I'll get in a groove with it, but usually I just post even at best.
Also, I tried switching my SMG to the Mini-Uzi from the popular UMP. I wouldn't say that I like it any more than the UMP, but there isn't any downside to it, you just need to watch your ammo consumption. I like it a bit more because it's less popular, so I'll stick with it.
I'm max level again after prestiging once, still haven't got my nuke. Things always seem to go horribly wrong when I get close, I've had people spawn right on top of me or right behind me being 20-24 more than once now.
Personally, I find the most satisfying thing is beating organized teams. The other night I joined a ground war mid-game and was the only pub on TF141's side. I messed around, didn't do too well, they made fun of me post-game. Got put on their team for the second match, turned it up but didn't play aggressively, went 14-2 or something in a TDM. They talked more shit post-game. Finally got on the other team for Domination in sub-base, took out my scavenger-stopping power-M16 class with predator-harrier-chopper gunner. Went 73-4, best score I've posted, we won, boy was that post-game hilarious.
