I've finally had some good Domination games of late. I get on a team that gives a shit about capturing flags and doesn't just roll over like a wet noodle. I've also taken to equipping myself with a smoke and C4 rather than my usual flash + semtex. I'm liking the C4 a lot - since there is no bomb warning when it's thrown, I've gotten several unsuspecting people that otherwise would've run away from a nade warning. The smoke is of course useful for capturing a flag.
I also finally got my akimbo Glocks, which aren't as much fun as I had hoped. A shotty is still a better secondary for me.
Now that I've pretty much finished the weapons challenges I want, I'm thinking of Prestiging. I love running around with Marathon/LW/Ninja and my Vector, but I think I'd have more fun starting over.
