I actually had the chance to play this myself on Xbox 360 at a friend's place the other day.
First tried TDM, ended up running around while people camped, left about 2 minutes in.
Domination was better, though. It just seems so pathetically easy to pick up and wreck people, even the ones that have been playing longer than I have.
I used that pistol grip pump shotgun for ****s and giggles and absolutely destroyed one lobby for about 4 games. Later on I had to quit because I was gonna pass out from laughing so hard. Someone killed me with a MINIGUN walking around like Dutch from Predator, and I was running around with two ridiculous looking shotguns in both hands just steamrolling people.
There are so many killstreak types, grenades, and general stuff to piss people off it makes me realize why people would rather camp and let their equipment kill people for them.
I'd say Black Ops and even MW2 are 75% upgrades and equipment spam, and 25% actual FPS skill.
